Prepare Your Blender: Place the jug of your blender onto its base. Make sure it's clean and dry.

Add the Ingredients: Add the 500g of frozen pineapple chunks directly into the blender jug. Pour over 150ml of coconut water and the juice of one lime. If you're using a sweetener, add one tablespoon of maple syrup or honey now.

Start Blending: Secure the lid on the blender. Start blending on a low speed to break up the big chunks of pineapple, then gradually increase the speed to high.

Blend Until Smooth: Blend for about 45-60 seconds, or until the mixture is thick, smooth, and has a consistent sorbet-like texture. You might need to use the blender's tamper (if it has one) to push the fruit down towards the blades. What works best for me is to pulse it a few times first before going to a full blend.

Check Consistency: Stop the blender and check the texture. If it's too thick for your blender to handle, add the remaining 50ml of coconut water and blend again for a few seconds. Be careful not to add too much liquid, or you'll end up with a smoothie instead of a slush.

Taste and Adjust: Give the slush a quick taste. If it’s too tart for your liking, now is the time to blend in another tablespoon of maple syrup.

Serve Immediately: Pour the frozen pineapple slush into chilled glasses. Garnish with a fresh pineapple wedge on the rim and a sprig of mint, if you like. Serve right away with a spoon or a wide straw.
