Considering making pickled vegetables

As long-standing readers here may have noticed, I like the idea of making from scratch at home products which are often bought as ready-made commercial products. I’ve had a reasonable amount of success with soya bean milk, tofu and salted eggs, which are all very easy.

I’ve also considered making soya sauce at home. While it can be done, as I mentioned in my earlier posting, I’ve decided not to try (at least for now) after chatting to a food scientist who used to work at Kikkoman. During the commercial production process at Kikkoman factories, there is assiduous testing to make sure that the fermentation process does not attract toxic microbes instead of the ‘right’ kind of bacteria, which can easily happen. I’ve also heard how difficult it is to make tempeh at home, and I assume it’s partly for those same reasons.

Another type of food I thought of making at home is Chinese pickled vegetables: mui choy, chye poh, kiam chye — all the things that would give the right ‘kick’ to my somewhat bland dishes. Today’s Sunday Times food question column by Chris Tan addressed this precise issue. The bad news is:

They are not as easy to make as they might seem, requiring successive rounds of drying, seasoning, salting, brining or steaming. These methods may look simple or crude but they are very sensitive to the quality of the starting ingredients, the ambient humidity and temperature as well as the microbes naturally present in the immediate environment.Hence, an experienced eye is needed to tell if the fermentation or preservation is proceeding correctly. Doing this kind of multiple-stage preserving at home is very tricky, frequently entailing much trial and error. Therefore, nowadays most people are content to leave it to the specialists.

The good news is that “many Asian cuisines have easy recipes for mildly sour, briefly fermented pickled greens that are designed to be made and consumed within a few days.” Examples of pickled gai choy, which is a kind of mustard green, include Laotian som pak, Filipino burung mastasa and Vietnamese cai chua or dua chua.

The advice from Chris Tan concludes with this advice:

The Japanese pickling tradition also has many quick pickle recipes. For a good introduction to methods and ingredients, I recommend the book Tsukemono: Japanese Pickled Vegetables by Kay Shimizu.

I don’t have that particular title, but have already been pouring over TSUKEMONO―Japanese Pickling Recipes (Quick&Easy) which is part of my collection of food books. Unfortunately, I’m not familiar with how the different types of Japanese pickles taste and I’m not a big enough fan of pickles in general to go all out on experimenting. I wonder if quick pickles will taste more like nonya acar, rather than anything like chye poh…?
