I love making lasagne, it's a really lovely cosy task on a wet or cold weekend day!
I make it from scratch (including the pasta), but I do cheat and use a frozen soffritto mix, as I get bored by all the chopping.
I have the ragu simmering on the stove for hours, frequently topping up with a bit of red wine (both me and the ragu!). The kitchen smells lovely and rich and full of wine-y comfort.
DH makes the pasta, I make the betchamel.
We make 3 or 4 and fill the freezer.
Now it's getting a bit autumnal, I rather fancy a Lasagne Saturday.
Fish pie, on the other hand, I hate making and find it a proper faff. Fish stock, plus hard boiled eggs, plus poached fish, plus potato peeling and making mash. Just too faffy for me. And fish pie doesn't making the kitchen smell warm and wine-y. Instead the kitchen smells fishy and unpleasant.
