I can think of many reasons for choosing a soup maker, many of the technical and totally boring to read, but bearing that in mind, these are the most common answers to the question of why choose a soupmaker.
Fresh pureed soup in 21 minutes and chunky soups in 28. Compare that against how long it takes you to make a pot of soup on the hob. There have been times when I’ve made two batches, one after the other where I have a larger group to feed, yet don’t want to have to check on it every five minutes like I would in a pot
What can I say? When I made soups in a pot, they took far longer to cook than the paltry 21 minutes it takes to make a smooth version in a soupmaker.
If you buy a saute version, it’s all in one pot. No more frying pan for the onions, then into the soup pot.
Did you hear me say one pot? I’ll say it again. ONE POT. And maybe one wooden spoon to stir it with, and that;s it. And many of the soup makers are coated for easy cleaning.
Overboil, where liquid spills over the top of the pan and onto the rings below, used to be my biggest failing when I made soup. I no longer have that problem. Soupmakers never overboil unless you are not following the manufacturers instructions, or overfill the machine.
