How to Make the Recipe

Step 1: Combine Ingredients

In a medium saucepan, combine chopped rhubarb, water, sugar, and quick-cook tapioca.

Step 2: Cook the Mixture

Bring to a gentle boil over medium heat, then reduce to a simmer. Cook for about 10–15 minutes, stirring occasionally, until the rhubarb is soft and beginning to break down and the sauce starts to thicken.

Step 3: Cool and Serve

Remove from heat and let the sauce cool. It will thicken slightly more as it cools. Serve warm, chilled, or at room temperature depending on your preference.

Tips for Making the Recipe

• Use fresh, firm rhubarb for the best texture and flavor.
• Chop rhubarb evenly so it cooks at the same rate.
• Adjust sweetness to taste depending on how tart your rhubarb is.
• Let it sit after cooking to allow the tapioca to fully thicken the sauce.
• Don’t overcook—rhubarb breaks down quickly and can turn mushy if left too long.

How to Serve

Rhubarb Sauce is incredibly versatile. Serve it:

• Over vanilla ice cream or frozen yogurt
• Swirled into plain Greek yogurt or oatmeal
• As a topping for pancakes, waffles, or French toast
• Alongside roasted meats or pork as a sweet-tart contrast
• Spoon it over cheesecake, pound cake, or panna cotta for an elegant dessert
