|Blackberries||1 1⁄2 Pound (Thawed If Frozen)|
|Sugar||1 Cup (16 tbs)|
Put the blackberries into a saucepan with the sugar.
Cover and cook gently until the blackberries are very soft, about 20 minutes.
Sieve the blackberries and their juice, through a nylon sieve to make a puree.
Add a little more sugar to sweeten, if necessary.
Pour the sauce into a jug and serve hot or cold.
