Let's go to the restaurant first. You can cook more peanut bud dishes for the restaurant. As long as the price is reasonable, most restaurants will be willing to accept new recipes.
Make some pamphlets about the benefits of peanut bud by yourself, perhaps by memorizing them, and just go to the restaurant and talk to the chef.
Can also be wholesale to market stalls, it is best to do brand promotion or something, so that consumers can see it as soon as they pass by.
