From a website http://www.cookitsimply.com/recipe-0010-0162c96.html Treacle Tart like my mom used to make.

• Ready In: 40 mins
• Serves: 4
• Yields: 1 tart

Ingredients

• 6  ounces  shortcrust pastry, rich and sweet
• 4  ounces unsalted butter
• 8  tablespoons golden syrup
• 2  eggs, beaten
• 4  tablespoons  double cream (or single cream if you prefer)
• 2  lemons, zest finely grated

Directions

1. Line a shallow 23 cm (9 in) tart tin with the pastry and pre-bake or bake blind.
2. Pre-heat the oven to 200°C (400°F) Gas 6. Put a baking sheet in the oven to pre-heat.
3. Gently warm the butter and syrup together in a pan - just enough for the butter to melt but not letting the mixture get too hot. Remove the pan from the heat and allow the mixture to cool a little.
4. In a bowl, whisk the eggs, cream and lemon zest together. Gradually whisk in the warm butter and syrup mixture, then pour the mixture into the pre-baked pastry case.
5. Place the tart on the baking sheet in the oven and bake for 25 - 30 minutes or until the centre is set.
