Brought a tagine and a great Moroccan cookbook over the weekend. So far I have learnt the following:

a) Tagines change temperature slowly compared to a gas hob, don't turn them up and leave them - they make a mess.

b) Pay attention to measurements when it comes to mixing spices, to much chili IS a bad thing.

The cookbook is made in morocco, brilliant book, even if you don't want to make any of the recipe's, wonderful photography.
