Ricotta and lime pancakes

Ingredients (serves 2)
3/4 cup plain flour
1/2 teaspoon baking powder
1 tablespoon brown sugar
1 egg, separated
2 tablespoons low-fat ricotta
200ml skim milk
1 small lime, rind finely grated, juiced
olive oil cooking spray
1/4 cup low-fat vanilla yoghurt
1 tablespoon honey
2 passionfruit, halved
lime wedges, to serve

Method
Sift flour and baking powder into a bowl. Stir in sugar. Make a well in the centre. Whisk egg yolk, ricotta, milk, lime rind and 1 tablespoon lime juice in a bowl until well combined. Add to flour and whisk until batter is smooth. Cover and set aside for 20 minutes to rest.
Whisk eggwhite in a bowl until firm peaks form. Fold gently into batter.
Heat a non-stick frying pan over medium-high heat. Spray with oil. Pour 1/3 cup batter into centre of pan and tilt to spread. Cook for 2 to 2 1/2 minutes or until small bubbles appear on surface.
Carefully turn and cook for a further 1 to 2 minutes or until golden and cooked through. Transfer to a plate. Cover with foil to keep warm. Repeat with remaining batter, spraying pan with oil before cooking each pancake.
Place 3 pancakes on each plate. Top with yoghurt and drizzle with honey. Spoon over passionfruit pulp. Serve with lime wedges.
