My daughter made some savoury rice at school today - enough for one person - if I want to make it for six people do I just multiply all the ingredients by six or is it more compacted than that?
That's what we do.If a recipe says serves 4 and we are cooking for 6-8 we double all of it and particularly with a rice dish.ie. Risotto the liquid is most important. However if there are spices like chilli to be used in the original recipe then it would be wise not to double that ingredient. :-)
I would multiply every ingredient by six.
Imagine making it for one. Then making it for one again. And again, till you’ve made it six times. Then tipping all six into a big bowl, it would taste exactly as it would have done following the recipe for one.
I'd also say roughly multiply the major ingredients by 6; however, I never follow a recipe's directions for the amount spices, herbs, etc...I just add to taste.
