This makes a large tart – you can halve this for a smaller tart. Use your favourite sweet short crust pastry. Blind bake.
9 limes, 1 orange, 10 eggs, 375 gms sugar, 575 ml cream
Juice and zest limes and orange. Heat and infuse for 10 minutes. Then strain.
Whisk in sugar and eggs to strained ingredients until thick and pale. Fold in soft whipped cream.
