Where can you buy berry flavored caster sugar?

It's unlikely you'll find "berry flavored caster sugar" in the typical grocery store.

Here's why:

* Caster sugar is a refined sugar with a fine grain, typically used for baking and drinks. It's generally not flavored.

* Berry flavoring is often added to other products like jams, jellies, yogurt, etc.

Instead, you have a few options:

1. Make your own: Add a few drops of natural berry flavoring to your regular caster sugar. This will give you a subtle berry taste.

2. Use flavored sugar alternatives: Look for sugar substitutes that are already flavored with berries. Some popular brands offer sugar-free options or options with natural sweeteners.

3. Mix regular sugar with berry powder: You can find freeze-dried berry powder, which you can combine with your sugar for a sweeter, berry-flavored mix.

Remember, "berry flavored" can be quite broad. You might be interested in specific berry flavors like raspberry, strawberry, or blueberry. Search for those specific flavors in your local grocery store or online retailers.
