What a delicious appetizer! So delicious that I will share the recipe: Take one avocado that has been in your cupboard for a least a week. It ought to be ripe, shouldn't it? It's been there long enough. Never mind that it is still hard. Cut it open. Find by taste and the look of it that it is in fact not ripe and not as delicious as an avocado should be. Consider throwing it away, but reject that idea as wasteful. Peel it. Try mashing it to make guacamole as planned. Find that it is too hard to mash. Hmmm, how to make it softer? Microwave it with some water for 1:30! Then drain it and mash it. Taste it. Not great, but edible. Add some salt. What could make it better? Nothing other than sweet, sweet mango sauce from your nearest Trader Joe's. Mmm, now it is good. Serve with tortilla chips and sausage (recipe follows).
