i have unlocked home and fancy ovens' recipes first, as i don't use this ovens for anything else (except when i need smth for goals or to-go orders).
but since souffe is now 5silver i/o 1golden, i don't know.
i guess i wd rather choose the recipe from appliance i have in duplicate (i mean, stove, for example. or barista machine - if you bought 2nd one. i didn't yet).
or you can check the output parameters: https://forums.storm8.com/showthread....=1#post1251851
and choose the max srvs etc... it's up to you
