Jalapeno condiment for pho
Through experimentation, I got the answer. The answer is rice vinegar, a little sugar, a little salt (not so much salt and sugar as to make the vinegar seem like "seasoned rice vinegar" as for sushi, just a pinch of each) and time. After two days in the fridge the sliced fresh jalapenos mellow a bit, but they seem even a little crunchier than when they were first sliced. To me they are superior in every way to any jarred jalapenos I've ever had. After four days, they seem more like "pickled" jalapenos and start to lose some of the crunch that makes them so nice. I suspect that they might use a different vinegar, but the slightly seasoned rice vinegar works just fine.
