In a medium stainless steel saucepan, stir together strawberries and sugar. Cook over medium heat, stirring occasionally, until sugar dissolves. Using a potato masher, press (or mash) strawberry mixture until no large chunks remain. (It will not be smooth.)
In a small bowl, whisk together 1 tablespoon (15 grams) cold water and cornstarch until smooth. Whisk cornstarch mixture into strawberry mixture. Bring to a boil over medium heat; cook, whisking constantly, until thickened and cornstarch flavor has cooked out, 1 to 2 minutes. Press mixture through a fine-mesh sieve, discarding solids. Stir in almond extract. Let cool to room temperature.
