I do the roasted tomatoes method.
Halve a kilo of toms and place cut side up in a roasting tin.
Add a couple of small cloves of garlic (skin on), and a couple of sprigs of thyme.
Season and drizzle olive oil over them.
Roast at 200c until the tomatoes are soft and begining to char at the edges.
While the tomatoes are roasting heat up 500ml of stock.
When the tomatoes are roasted, remove the roasting tin from the oven and pour in the stock.
Turn the oven down to 180c and return the tin to the oven for 10-15 minutes.
Remove the roasting tin.
Locate and skin the garlic cloves then return them to the soup.
Blend the soup until smooth.
OPTIONAL (but it is much better if you do this): sieve the soup to remove the tomato seeds and skin.
Serve with a dollop of creme fraiche.
