Strawberry and yogurt smoothie

Ingredients

• 500 g ripe strawberries, hulled
• grated zest and juice of 1 large orange
• 2/3 cup (160g) low-fat natural yogurt
• 1 tablespoon caster sugar, or to taste (optional)

• 4 small strawberries
• 4 small slices of orange

1. Tip the strawberries into a food processor or blender and add the grated orange zest, orange juice and yogurt. 
2. Blend to a smooth purée, scraping down the sides of the container once or twice. 
3. Taste the mixture and sweeten with the sugar, if necessary.
4. For a really smooth consistency, press through a nylon sieve to remove the strawberry pips, although this is not essential.
5. Pour into glasses. 
6. If you like, decorate with small strawberries and slices of orange, both split so they sit on the rim of the glass.
