I will be hosting a party and need to purchase a larger pot to cook gumbo for the number of guests I will be having. I currently cook gumbo in a smaller thick-bottom All-clad pot. The roux is peanut oil based and I do well cooking it in these pots I currently own. I am looking at purchasing a pot from a restaurant supply store and would like to know if these pots will work for making a roux/gumbo and if there are differences between cooking in an aluminum pot vs a stainless steel pot.
Aluminum 'Stock Pot,' standard heavy weight 3/16in (4 mm.)
or
18/8 Stainless 'Stock Pot' with 5 millimeter thick aluminum core
It seems the only large pots are categorized as stock pots. Are these too thin for my purposes?
