Finally got the goal that unlocked the hot sauce. I collected red peppers from my farm and ivy popped up and I had to give her 50 peppers, I think. Then I had to give 30 monster tails. Now I'm making the hot sauce in the kitchen, waiting to see what it does, 3 hours to make.
Edit: You need to be level 17 to trigger this quest. It is triggered by harvesting a hot pepper. If you are maxed on hot peppers you can still trigger this by harvesting hot peppers. It may take a couple of tries.
