In restaurants, jiachang-flavor dishes often use a bit more red douban-infused oil than you’ll find in versions made in home kitchens. The photo we show here follows that style, as it is what most people outside of Sichuan are used to. If you’d like this style of dish, use the maximum amount of red-oil douban and cooking oil called for in the recipe; if you’d like a subtler homestyle dish, use the minimum amounts called for.
