I'm looking for recipes and technique tips for a good white bean dip. I am particulary interested in something that serves as a dip for carrot sticks and other vegetables. I tried to make one last weekend with canned beans, olive oil, lemon juice, garlic and chili powder and didn't like it at all. Any tips are appreciated. Do you reserve liquid from the can? Does anyone use dried beans? Olive oil or another kind of oil? Vinegar or lemon juice?
