212. Meat and Fish

33:1 We do not eat fish with meat, even with poultry, because we have a tradition that it is a harmful combination. Therefore, one should not cook fish and meat together in a small oven unless one of them is covered. In a large oven, however, this is not problematic. 33:2 When a person eats either fish or meat and then desires to eat the other one, he should first cleanse his mouth by eating a little bread and drinking something.
