Yes, they sell the Nanak brand paneer (which is the one I prefer anyway). Only some locations have it. There are some applications I like to use homemade paneer, and others where I like to use the denser, store bought paneer. In store, they only sell the 14oz block, but it’s cheaper than buying the same product at the Indian store.
Valley Produce sells both the 14oz block and the 2.5-3lb block. I want to say it’s around $15.99.
Pretty sure it is. You can be a chef and not a business owner. You happen to be both, but they are independent of one another.
Unless you plan on making your own chutneys, which is sounds like you don’t plan to do, you’ll have to see if you can get a restaurant to sell them to you. Indian chutneys are usually made and eaten fresh because they contain fresh ingredients (mint, coriander, green chillis, etc)
