FAQs

1. Can I use different types of tofu instead of aburaage?

Yes! While aburaage (deep-fried tofu pouches) is traditional, you can substitute with regular firm or silken tofu, though the flavor and texture will differ slightly. Silken tofu might break down more easily in the broth.

2. What can I do if I don't have mirin?

A small amount of sugar (about 1 teaspoon) mixed with a splash of dry sherry or sake can be a good substitute for mirin. Adjust the sweetness to your taste.
