Coulis. My dear, coulis. Pronounced kool-eeh. Snerk!
Pound for pound of fruit and sugar, few tablespoons of lemon juice, tiny pinch of salt, and cook down to desired consistency. You might need to bash the fruit down if it's tough. (not pears, they ooze flavor when ripe, when green... Doc will tell you that you'll get over it). Cornstarch can be added ( pre-mixed in a little cold water) if it's too thin, but you should probably be patient. Strain the result.
That's coulis for every fruit in the world. Exceptions may exist. GRIN!
