I agree but depends what you’re cooking in it.
Agreed – and there are lots of soup recipes that recommend doing different things at different times (ie, char-grilled red pepper soup (obviously) needs the red pepper char-grilling before putting it in the pot otherwise the taste just wouldn’t be correct. However the soups I make are all very simple and can be put in together (lentil, potato & leek, butternut squash, mushroom, sweet potato etc). As a convenience tool it’s great as I can prepare everything the night before and then just bung it in and switch it on when I get up and it cooks/blends whilst I get my kids ready for school/make packed lunches etc.
