This year I have Sweet Genovese, an Italian basil from Genoa, Hot & Spicy (from Critter) and Holy Basil that just popped up from last year. I had a setback this year so not as much as usual but I know that the basil can take the heat since it's been so hot this year!!! LOL
I am drying much of the Holy basil this year to use in teas - it's said to be a great diuretic and sometimes added to "diet" tea blends.
The others I just put directly into zip lock baggies, flatten and put in the freezer. This way, they don't take up too much room in the freezer. Also make a pesto and put in the little muffin tins, then freeze and they pop out easily, store in ziplocks or those little plastic containers in the freezer.
But have to say I dropped the ball this year and it is already going to seed.
