For Chinese hotpot styles it takes a bit of a commitment.
It’s becoming easier and easier to find ready made packs of Sichuan hot pot bases in shops that sell East Asian ingredients, but I don’t know what the carb content of these are as I make my own.
I have a wonderful book by Mandy Lee called “The Art of Escapism Cooking” which gives lots of ways of introducing big bold exciting flavours into your food.
One of the recipes is for a delicious chilli oil. It is covered in this video
It’s the sort of oil that can transform something you may have already eaten the day before. For instance, French Pot Au Feu, which I love, I can make a huge batch and have it two days in a row as the chilli oil completely changes the flavours.
There’s a recipe on YouTube called “My favorite Sichuan Hot Pot recipe, from 1972” which explains how to make a base to enrich the soup flavours further, but it uses quite a few bean based pastes, which are high carb. The main one is doubanjiang, and as it has so much flavour you won’t need that much in your eventual soup. This is why I like using the chilli oil as I don’t need to lean quite so much on the bean based condiments.
Another key is getting GOOD Sichuan peppercorns, vibrant red, strong, delicious citrus scent and the make your mouth tingle like a school bell is ringing inside of it.
