Melt butter in a large frying pan over medium heat. Stir in blackberries, blueberries, 1/4 cup sugar, and 1 tbsp. lemon juice. Cook until juices are released from fruit, about 4 minutes. Stir in thyme, then raspberries. Add more sugar and lemon juice to taste, depending on sweetness of berries. Serve warm over ice cream.

Very easy to make and the flavors were incredible. I paired it with organic vanilla bean ice cream and it was a big hit with everyone. Kids loved it too! Thyme is one of my favorite herbs; it really enhanced the other flavors. I can't imagine anyone not liking this. I didn't have any blackberries so I just used double the blueberries with no problems at all. I did have to add a little more sugar and lemon juice; be sure to test the flavors before serving and add a little more if needed as the recipe suggests. Extra sugar and lemon never hurts.
