I've noticed that a lot of Mums rave about pesto. I've never tried it because it contains pinenuts and because DH has a severe nut allergy, DTS have never been given any nut products (they are 2yo 11 months).
If I made a thick tomato sauce using tomatoes, tomato paste, garlic and basil, would that be similar to pesto but without the nuts? Or do you need nuts to have the unique taste of pesto?
