Ilama quality varies radically, on the same tree in different years, from heavenly to not fit, due to Florida weather. We had way too much rain for too long this year, but now is drier. It is also quite late in the year.
Ilamas are tastiest when there is little rain during most of the fruit's development, and then heavy rain just before and during harvest. That is what pretty consistently happens in western Guatemala and El Salvador. There, most of the ilama harvest is in August. They also have good volcanic soil.
