Spread ricotta mixture over pastry pieces, leaving a narrow border. Top each with 2 slices tomato
Bake at 220°C for 10-12 minutes or until puffed, golden and cooked through
Meanwhile, pat capers dry with paper towel. Heat oil in a small saucepan over medium-high heat, add capers and fry for 3-4 minutes until crisp. Remove with a slotted spoon and drain on paper towel
Top tartlets with flaked trout, capers and extra basil. Serve warm or at room temperature
Tips & Hints:
Swap the trout with smoked salmon if it is more to your taste. This recipe is equally delicious if you leave the trout off altogether, for a vegetarian option. If you are feeding a crowd, this recipe is easy to double or triple.
