I have tried three times to make mayonnaise with Crisco vegetable oil and it absolutely will not emulsify. I have been successful using olive oil. Is there something wrong with the oil? It seems pretty thin, certainly thinner than the olive oil I use? I bought the oil at grocery outlet which is a discount store. It doesn't smell bad at all, but it is pretty liquidy. I have used a full bottle trying to experiment and figure out what I am doing wrong.
