Trim off strawberry tops, then chop the strawberries roughly.
Add to a food processor, along with the sugar and the orange juice.
Purée for 20 seconds, then scrape down the sides with a spatula. Purée again for another 20 seconds, until smooth. The coulis should be a deep raspberry color.
Strain through a fine sieve to remove seeds and any hard or unripe pieces of strawberry.
Store in a mason jar in the refrigerator, or in another airtight container.
Notes
Storage Tips:Put into an airtight container like a mason jar and keep in the refrigerator for up to 4 days. This strawberry coulis also freezes well, for up to 3 months. Try pouring it into an ice cube tray to freeze in small amounts. Defrost overnight in the refrigerator before using—you may need to whisk it well to bring it back to the perfect consistency.Expert Tips: No food processor? Try using a regular blender or an immersion stick blender instead. You’ll get a delicious strawberry sauce either way.This coulis is fairly thick—pour slowly through the sieve and push down on those solids with a sturdy spatula.Want to use regular granulated sugar instead of super-fine sugar? That granulated sugar will dissolve the best if the mixture is cooked. Combine sugar and strawberries in a saucepan and cook gently over the stovetop for about 8-10 minutes over medium heat. Stir to make sure sugar is totally dissolved.
