*Selecting the perfect avocado is crucial for this recipe! A ripe avocado will turn from its dark green color to an almost black-green shade. You will also need to do a squeeze test in the store because non-ripe avocados are hard as a rock and will not work in this recipe. They should feel a bit soft but not squishy. If you buy a few that are not quite ripe just leave on the counter to continue ripening. Store them in the fridge to slow the process down.
