There are two slightly unusual herbs which grow well in my garden and whose first emergence always inspires me to cook my favourite recipes with them.
One is Sorrel which I make into the easiest possible of soups - tomato and sorrel - with the added bonus that it is equally good hot or chilled with a little crushed ice added.
The other is Lovage - a rather large and potential thugish plant resembling celery in appearance but with a decidedly aniseedy flavour. While the young leaves are edible, the stems are best used for flavouring. I use it in another very easy but delicious casserole with onions, garlic and dry Martini(!) - adapted from a Judith Hann recipe for Guinea fowl - which works equally well with corn-fed chicken.
I have just discovered Hann's Herbs: http://www.hannsherbs.co.uk/tours.php Looks like the most wonderful day out either to the garden or cookery classes - and she was lovely to work with.
