Soy substitute week

This week has been a week for experimenting with soy products to stand in for eggs and dairy. The impetus and guide for the experiments was the book Tofu and Soyfoods Cookery by Peter Golbitz, specifically the recipes Mock Sour Cream Tofu Dressing and Scrambled Yuba.

Experiment 1: vegan mushroom stroganoff sauce, with Mock Sour Cream Tofu Dressing based on silken tofu standing in for sour cream. The basic ingredients are silken tofu, oil, lemon juice, and salt. I served the sauce over no-yolk egg noodles. I am perfectly comfortable putting vegan sauce on non-vegan noodles, but I would have used other noodles if I were serving actual vegans.

The results here were mixed. The sauce's flavor, which I initially thought was too lemony, settled down by the time I ate leftover noodles the next day and I liked how closely it tasted to sour cream. Better than other packaged soy sour creams I've purchased in the past. The texture was disappointing. The oil tended to separate out, making the sauce greasy instead of creamy and smooth. I think if I were going to make this dish again, I'd prepare the mock sour cream with a stabilizer like cornstarch or mustard or something and do it a day ahead to let the flavors blend.

Experiment 2: scrambled yuba, which I served on toast. This no longer seemed like a breakfasty scrambled egg dish when I added carrots, onions and mushrooms, nor did the garlicky tamari-flavored seasonings recommended scream breakfast to me. It was a nice light dinner.

Major challenges included finding yuba and making it taste like something when I didn't have all the ingredients called for in the recipe.

First, how I found the item. The owner of my favorite local Asian grocery had dried yuba on hand, but he didn't know it right away because he was not familiar with the Japanese name yuba for the product. His native language is Chinese, but he understood exactly what I wanted when I described it in English. Yuba is the skin skimmed off of boiled soy milk. I wasn't prepared to make gallons of homemade soy milk and skim its skin to get fresh yuba, and frozen just isn't available in my area.

Second, yuba does not naturally taste like anything. This ingredient is mostly about texture, like tripe or oatmeal. To borrow a phrase from Douglas Adams, it is almost, but not quite, entirely unlike scrambled eggs. No fluffy softness. No eggy richness. No buttery finish. Not even yellow, more like beige. In the pan, it vaguely looks like slices of very thin fried egg whites. I had run out of nutritional yeast flakes and forgot to get some for this dish, so therefore I didn't have the most essential flavoring called for in this recipe. I decided not to worry about it and make it taste entirely different. I used sweet soy sauce (kecap manis), garlic powder, chicken broth powder, the above-named vegetables, and sesame oil and fresh parsley for garnish.

If the goal here is to make something that is like scrambled eggs for breakfast, the experiment failed. I believe it would continue to fail even if I had followed the recipe exactly but with my dried yuba. Reconstituted dried yuba does not look, feel or taste like egg. I don't know whether the fresh or frozen could entirely take care of these issues, but it would at least probably be closer in texture to slightly overcooked eggs. The nutritional yeast flakes would have lent a more cheese-like flavor. If the goal is to make a yummy protein and vegetable dish with a new food, I think the experiment was successful. My husband and I like yuba enough to try it again sometime in the future. The possible flavors to combine with it are endless, so we'll keep trying new ways of preparing it.
