"Warning: Pickled watermelon radishes are not like traditional pickled radishes. Upon fermentation in the fridge, the radish slices undergo a dramatic transformation, releasing a smell that might make you shudder. That said, the slices themselves taste much milder than they smell, and with a little breathing time, their pungency tempers. I find them addictive -- they are the perfect condiment in a bánh mì sandwich or in a whole grain bowl or in anything that needs that acidic bite. These pickled radishes will last indefinitely stored in the fridge but are best eaten within 3 months. Source: David Lebovitz..."
