How to Make Superfine/Caster Sugar

Sometimes a recipe will call for superfine or caster sugar. When you go to the store you will also find this sugar called ultrafine sugar, baking sugar, and/or castor sugar. But it isn’t anything special and you don’t need to pay a premium price for it because it is easy to make yourself. All you need is white sugar and a food processor or blender.

The granulated sugar on the right is regular white sugar. The sugar on the left is superfine or Caster Sugar. Superfine sugar can be used cup for cup for regular granulated sugar. When you use superfine sugar instead of granulated sugar? Use superfine when you have a recipe where you need the sugar to dissolve quickly but don’t have a hot liquid to help, like when you make a meringue pie topping.

    If I don’t have a food processor, what setting in a blender is needed to do this and does the amount of blending time change?

      try a (cleaned out) coffee grinder. Don’t grind too long or you’ll get powder.

    Thanks so much for this recipe, I could not even find the sugar in a store and I really didn’t have the time to order it. 🙂

Welcome. I'm Alea!

On Premeditated Leftovers I share simple recipes made with whole foods, practical shopping tips, time saving techniques, and meal planning strategies. I also share tips for minimizing food waste, so more of the food that is purchased ends up on the table.

While volunteering as a budget counselor, I realized that food is the element of most people’s budgets where they have the greatest control. I set out to develop low-cost recipes from scratch to prove it’s possible to create delicious meals on a limited budget. Eating well while spending less is about more than just creating recipes using inexpensive ingredients; it’s about creatively combining ingredients so you don’t feel deprived and are inspired to stick to your budget.
