Soup is made in the pressure cooker which cuts the cooking time by at least half and so saves on the gas. Since I cook only small quantities of potatoes and other veg, it's cost-effective to use the microwave - 5 minutes instead of 25 on the hob. I buy a kilo of carrots, use half for carrot and coriander soup and freeze the rest.
