THERE ARE FASCINATING THEORIES as to the origins of this vegetable relish. None is conclusive, but I tend to buy the idea that its origins are Indian or Persian, because of the turmeric and other spices. The preparation has become an American classic, made from end-of-harvest vegetables that almost always include cauliflower. Chowchow, today, is a superb salsa to be scooped up with crackers, pita, or pappadums (lentil chips).
3 carrots, halved and roughly chopped
3 stalks celery, roughly chopped
Florets from ½ head cauliflower, roughly chopped
2 bell peppers, seeded and roughly chopped
3 cups rice wine vinegar
1 slice fresh ginger
1 clove garlic, smashed
6 tablespoons sugar
2 tablespoons salt
1 teaspoon ground turmeric
1 teaspoon coriander seeds
½ teaspoon mustard seeds
1 bay leaf
Pinch crushed red pepper flakes
Put the carrots and celery in a food processor and process until finely chopped. Add the cauliflower and peppers and pulse briefly.
In a medium saucepan, combine 1 cup water, the vinegar, ginger, garlic, sugar, salt, turmeric, coriander seeds, mustard seeds, bay leaf, and red pepper flakes and bring to a simmer. Once the sugar has dissolved, add the chopped vegetables and return to a simmer, stirring occasionally so all the pieces pick up the color from the turmeric. Immediately transfer the contents of the pan to a large bowl and let cool to room temperature.
Using a slotted spoon, transfer the vegetables to a covered container and add enough liquid to cover the vegetables. The Chowchow will keep, covered in the refrigerator, for about a month.
