I have my LL soups heated in the microwave- it is MUCH better at getting rid of lumps than adding hot water. I do them for a minute then whisk then for another two minutes, whisking again (with fork is fine) at the end- lovely! But keep an eye- I use three different microwaves between work and home and rented flat and the one at work is fierce- boiled over one day and I lost half my soup:cry: and it was a bugger to clean up!
