I started a batch of Indian spice flavored pickles a bit after Christmas. I put cauliflower and two kinds of carrots, regular orange ones and some beautiful red tinged ones, in my half-gallon fermenting jar. I added garlic, cardamon pods, cumin, and coriander. After a few days the brine turned a lovely shade of pink. By the end of the fermentation time. The carrots were all now orange and the cauliflower is pink! Not so sure that they look appetizing but they taste great.
