Hey guys - I know a chef. She's a teacher at a local culinary school, and a good friend of my mum's. She also caters if needed. She comes to your house, and charges (I think) 100 soles for 3 hours of cooking lessons. There is so much food prepared, you're usually set for 3 or 4 days! She sends you the list of ingredients beforehand, or if you prefer, she can go with you to the market or grocery store and help you pick the best ingredients and fresh produce - this options is great if, like me, you're learning from scratch!
Her name is Marisol - contact me via PM if you would like her details. I don't want to post her number out there, you know? She's super cool.
