The Perennial Paddock: Goji Berries

I planted Goji berries years ago when I was interested in eating the berries, and hadn’t yet discovered how invasive they were. I am told that they like slightly alkaline soil, and indeed mine revel in it and come up everywhere despite whatever obstacles I put in their way.  But as far as I’m concerned their invasiveness is a positive boon, since my favorite part of the plant is the young shoot.

Gojis want to ramp away into big lanky vines that sprawl everywhere and don’t bear much fruit,  but some trimming helps them settle down and stick to their work.

I tie mine to fences or stakes about 40 inches above the ground, and then in the spring I whack off everything above that point.  There is no artistry involved in this pruning; you can do it with a hedge trimmer.  Then they grow new branches which drape down artistically from the point where they are tied, and are covered with fruit in season. They are very ornamental and can be grown in the front yard.  They are also highly drought  tolerant once established. The fruit tastes rather like a tiny tomato with a hint of bitterness. I use it mostly for fermenting into hot sauce and making superfruit sauce.  You will find material online suggesting that the berries will prevent cancer and Alzheimer’s and make you live longer. I don’t get excited about that kind of talk, and I hope that you don’t either. They do have a good nutrient content, including doses of lutein and zeaxanthin that might be useful in helping to prevent macular degeneration, however be aware that the berries have not been researched for that purpose.

My favorite part of the plant is the young shoots that come up in places where I don’t want them, so I can pick them and eat them.  Please note that the shoots are only edible when they are young, tender, and snap cleanly off as soon as you try to bend them. If they will bend without snapping, they are not fit to eat.  I chop a bundle of shoots into fine cross section, about 1/4” lengths, and stirfry with some garlic, ginger, and soy, and find them very good. If the stems are getting wiry and bendable, you can still harvest the leaves and add them to mixed greens or cook them lightly in a Thai-style curry.

Now, about those health claims: I find two opposite sets of claims being made about Goji berries and leaves (the leaves are widely used for tea in Asia and are used in traditional Chinese medicine.) One is that the components of both leaves and berries include multiple antioxidants and compounds that act as anti-inflammatories in vitro and in vivo. This view is based both on their traditional uses and on the fact that multiple flavonoid antioxidants have been identified in both leaves and berries.

Below is a link to a simple analysis of components of the leaves.

Below is an analysis of anti-inflammatory activity in extracts of three berry species, including Goji berries, in vivo in mice.

The other point of view is that, as a distant member of the nightshade family, this plant should be avoided in its entirety. I have not found any credible research suggesting that the vast majority of us have any reason to avoid nightshades. I also don’t find it credible that a plant which contains numerous compounds that have demonstrated anti-inflammatory activity both in vitro and in vivo (beta-sitosterol, betaine, and hydroxycinnamic acid amides, to name only a few) would suddenly become inflammatory when eaten. If you feel that eating gojis makes your stomach burn or your joints hurt, by all means avoid them.  You are the author of the owner’s manual for your own body.  But to go from there to saying that nobody should eat them is quite a leap, and ignores demographic evidence.

This is a picture of goji berries being grown commercially in China, apparently staked up in more or less the same way that I do it but more neatly and artistically.  When covered with their fruit in summer, they are as radiant as Christmas trees.

 

 

Orange Peel in the Thrifty Kitchen

I’m  an almost-diabetic who uses low-carb food intake to maintain my excellent blood sugar, so citrus juice, which is a pretty concentrated belt of sugar, is mostly out of my diet.  I also love oranges and orange flavored things, and don’t like artificial flavors. So for a while I have been following with interest the analyses showing very high antioxidant activity in citrus peel and wondering how to incorporate it into my diet, and recently I got a chance to test this when I came across a bonanza of 20 large organic navel oranges that could not be sold because they had soft spots. I could have made orange-cello liqueur, but wanted something I could drink with lunch.  So I washed the oranges carefully, cut out the soft spots, cut them into chunks, and puréed  them in batches in my blender with only enough water to keep the purée  moving.  Each batch was blended at the highest speed for over a minute, to make sure it was completely liquefied.  I have a Vitamix, and I don’t really know how well this would work with other blenders, but probably well enough.

Please note that the oranges I was using were seedless. If you try this with seeded oranges, the seeds have to be carefully removed because they are intensely bitter, and this technique will not work at all with lemons because their inner white pith is so bitter.  I haven’t experimented with other citrus. I would say that tasting a little slice of the white pith might be a good test. If it’s very bitter, it might not work to use it this way. I think that blood oranges would work well, and I plan to try as soon as they come into season. Also, organic really matters when you are using the peel.

You end up with a thick smooth purée  that is only very slightly sweet, has a hint of bitterness, and is loaded with orange flavor and all the nutritional value than oranges have to offer. I use two or three tablespoons in a water glass, fill it with sparkling water, and sweeten with stevia sweetener. When you get near the bottom of the glass, be sure to swirl it around and drink up all the particles that settle to the bottom. Overall I’m probably taking in about a tablespoon of pure orange juice per glass, so the carb content is not high enough to worry me. I have also added it to a low-carb coffee cake with good results. Because of the intense flavor that the peel adds, you don’t need much.

Orange trees are strikingly beautiful, and if you live in the citrus zone they are great edible landscaping material.

If you do a web search on citrus peel you will find articles suggesting that there are few diseases it won’t prevent or cure. Let’s not get carried away. The antioxidants that it contains, including  naringinen, hesperadin, and rutin, have some interesting anti-inflammatory activities, and there is no documented evidence that ingesting some amount of citrus peel and pith is harmful. It’s also a superb natural source of vitamin C, which can be a bit short in a ketogenic diet. It makes thrifty use of something ordinarily discarded, and it tastes good, adding strong flavor and a touch of bitterness that makes an adult drink out of a fruit that can otherwise be too sweet to enjoy very much of. You can read about its various possible benefits at the links below, including the interesting demographic information from the REGARDS study that higher levels of citrus consumption correlated with lower levels of ischemic stroke. Make of that what you will.

There are other possibilities for eating citrus peel. I came across the following recipe while searching, and haven’t tried it yet, but it does look lovely, doesn’t it? Personally I would roast the fruit-veggie mixture first to soften them more, then the salmon by itself, since I despise overcooked salmon.

My Southeast Asian Summer: Turmeric

_Media Card_BlackBerry_pictures_IMG00146

      Turmeric and its constituent components the curcuminoids, a complex of antioxidant and anti-inflammatory compounds, are getting attention and medical research dollars these days. But this blog is not about disease treatment or medical research, it’s about healthy and delicious food, and turmeric is here for its culinary qualities.  Both the roots and the leaves are a common seasoning in many parts of southeast Asia, and the leaves are impossible to buy in this area, which led to my experiments in growing them. It’s a tropical and needs to be brought indoors when the nights start to cool off, and during the summer it needs light shade and plenty of moisture. Initially I bought plants from an herb supplier, but since then have done better with plants I started at home.

       You need some roots from the store to get started. Put them on top of a pot of good organic potting soil and press them into the soil. Put in a warm place (a seed-starting warming mat will really speed things up,) keep moist, and within a month you’ll see small buds growing off the roots. In another month or so, you’ll have turmeric leaves to use.  It will prosper in a sunny window over the winter, but does best if it can go outdoors in the summer. Remember, part shade is important.

     To begin with the root, it can be grown in a pot but you are unlikely to get enough to use it freely. I don’t recommend the dried powder for most applications; to my palate if lacks the fresh vibrancy of the fresh root. I advise buying organic root, and you can often find it among the other fresh vegetables at La Montanita Co-op. Ask the produce manager if you don’t see it. It’s used in a lot of the seasoning pastes that I make for my southeast Asian cooking, so you’ll notice it in several of the recipes on this blog (use the search function to find them). But one of my favorite ways to use it is as a brilliant yellow-orange “juice” concentrate which I keep in a corked bottle in the refrigerator and add to water to make “sun juice.” The color alone is irresistible and cheers me up just to look at it.

     The leaves are large, glossy and handsome, and look attractive when the pot is brought indoors for the winter, but remember that any plant you’re always snipping at for kitchen use won’t look great for long. When cut they smell very like a fresh, sweet carrot, and I love to season carrots with them. Clich the link below the picture for recipes.
