A coulis is made from vegetables and fruits to enhance dishes. It is typically made from berries. This particular one is made from strawberries. Here is what you need to do for this:
1 cup strawberries – hulled and halved
1/4 cup sugar
Water to cover the berries
Place the strawberries in a pan and cover with enough water. Add the sugar and mix. Simmer for about 25 minutes. Strain the fruit and press well. Make sure you do not discard any pulp and get rid of all seeds.
Return strained strawberries into pot and simmer until reduced and thickened. Cool down and use for drizzling on desserts.
