Fit For a KingG 15

ok this is what happened to me.......i have the trait Natural cook, my cooking skill is 10, i have the most expensive oven and then randomly the achievement popped when i cooked a perfect French toast so my suggestion

Have the trait - Natural Cook, you can also change traits using the lifetime reward "mid life crisis"

cooking level - 10

Get the most expensive oven

Then just keep making French toast

hope this helps because it totally happened to me at random
