Do I have to strain it?
Nope. Straining gives you a smooth, pourable syrup that is great for drinks and drizzling. Leaving it unstrained makes it thicker and more jammy, which is elite on ice cream and French toast.
How do I make it thicker?
Simmer a few minutes longer and let it cool fully. Syrup thickens as it cools. If you want it very thick and glossy, mix 1 teaspoon cornstarch with 1 tablespoon cold water, then whisk it in and simmer about 1 minute until thickened and no starchy taste remains.
How do I make it thinner?
Whisk in warm water, 1 teaspoon at a time, until it pours the way you want. If it is cold and very thick, warm it slightly first.
Can I use frozen strawberries?
Yes. Use the same amount. No need to thaw, but it may take a few extra minutes to come to a simmer. Frozen berries release more liquid, so you may need an extra 2 to 4 minutes of simmering to concentrate the flavor.
Can I reduce the sugar?
You can, but the syrup will be less glossy and will not keep as long. Start by reducing sugar by 2 tablespoons, taste after simmering, and adjust. Strawberries vary a lot in sweetness.
Is this the same as strawberry sauce?
They are cousins. Syrup is usually more pourable and meant for drizzling. Sauce can be chunkier and thicker. With this recipe, straining makes it syrupy, leaving it chunky makes it sauce-adjacent.
