rancid home-made playdough?

rancid home-made playdough?

i figured id post this here because kids can burn through play-doh and it's much cheaper to make your own. i made some a coupla weeks ago, have kept it in an air-tight container and when we got it out today, it smelled like rotten eggs. it's not moldy - at least that i can see. has anyone elsed experienced this? is there a "fool-proof" recipe to try next time? it's not going to save me money if i have to make "fresh" stuff every month. fwiw, this is the one i used. 2.25 cups flour 1 cup salt 2 TBSP drink mix 4TBSP cooking oil 1 cup water
