I like tarragon but the stuff in the garden is skulking underground. Last year it waited until July to show itself. So when I noticed Tesco had packets of fresh tarragon - flown in from Israel - I bought some, wrapped it round some chicken and cooked it. Great! Really strong tarragon flavour.
Then I had an idea. I bought another packet and put some stems in a pot of compost. So I may end up with a supply of fresh super-strong tarragon both for the garden and the window ledge.
I was going to try the same with some lemon thyme but the flavour, although strong wasn't quite lemony enough.
