Kiwifruit and Spinach Smoothie

Ingredients

• 2 kiwifruit
• 1/2 apple
• 4 leaves spinach leaves
• 700 ml water
• 12 g caster sugar

Method

Prep your produce down to size before the blender touches it. Halve the kiwifruit, then quarter each half. Dice the apple into roughly 5 mm pieces — this matters because uneven chunks will blend unevenly, leaving fibrous bits that catch between your teeth. Strip the spinach leaves from their stems entirely; the stems are woody and will stay stringy no matter how long you blend. Tear the leaves into rough 2 cm pieces.

Layer the blender jug strategically. Put the water in first, then the fruit and vegetables, finishing with the caster sugar on top. This arrangement ensures the liquid reaches the blades immediately and begins breaking down the cell walls of the produce before friction builds heat. Sugar dissolves into the liquid during blending, distributing evenly rather than clumping at the bottom.

Blend in three 20-second bursts at high speed, pausing between each to scrape down the sides with a spatula. This approach is more effective than the stop-start method because it maintains momentum — the blades need continuous contact with the produce to rupture the cell membranes and release the juice. smoothie-making demands aggressive blending; timidity leaves you with texture rather than a proper drink. The kiwifruit will break down quickly, releasing its seeds and acid. The spinach resists longer — its cellular structure is tougher than the fruit — but the mechanical action will pulverise it within 60 seconds total. You'll hear the pitch of the motor change as resistance drops; this is your signal that the leafy material has surrendered.

Stop when the surface is entirely homogenous and fluid. There should be no suspended chunks catching the light and no foam layer — if you see either, you've underdone it. The cold-drinks category benefits from aggressive extraction because it creates a smooth mouthfeel and even flavour distribution. Serve immediately over ice or chilled straight from the jug. The drink will separate if left standing for more than 10 minutes; the heavier fruit particles sink and the liquid oxidises, dulling the colour and sharpening the astringency of the kiwifruit acid.
