Lime Margarita bars

one ingredient february 2014

Since Tuesday, when I visited Wahaca  I have been dreaming about margaritas.

Tamarind ones, hibiscus ones and top shelf gold tequila ones. Much as I’d like to it is just not fair on either my liver or my family to indulge in Margaritas as my sole form of liquid refreshment. Then I had an revelation. Using an idea taken from a friend who incorporates alcohol into every cake he bakes.  Could I make a margarita cake? I didn’t fancy cupcakes as I wanted that sharpness from the cake that makes your teeth squeak. Buttercream wasn’t going to allow me that feeling. Perhaps if I used lime curd? Then I remembered, Nancy Drew. In one of her novels she bakes  lemon bars. I hadn’t known what they were so did a little research. Lemon bars consist of a biscuit base and a lemon curd like topping. They then get dusted in icing sugar. What’s not to like? Nancy must have grown up by now, perhaps it is time for the Lemon Bars to do likewise.



150g self raising flour

80g icing sugar

110g butter very cold


2 large eggs

200g caster sugar

2 tbsp self raising flour

Zest of 1 lime

Juice of 1 lime

1 tbsp tequia

1 tbsp cointreau or triple sec

Pinch of salt

Icing sugar and sea salt to dust

How to….

  1. Pre heat the oven to 180C.
  2. Line a  12″ by 6″ tin  with baking parchment.
  3. To make the base sieve the flour into a roomy bowl, do the same with the icing sugar.
  4. Cut in the butter and rub in until the mixture resembles large breadcrumbs. Press the crumbs into the bottom of the baking tin. Don’t worry about being too tidy as the amount of butter in the mixture will allow the base to spread and level in the pan. 
  5. Bake in the oven for between 15 and 20 minutes until golden and firm.
  6. You can either allow the base to cool or pour the following mixture straight over the hot base it doesn’t really matter.
  7. The topping is made by whisking together the sugar, eggs, flour and salt. Grate the lime rind over the mixture as this captures the lime oils released as well as the rind. Whisk in the lime juice, tequila and cointreau and pour straight onto the base.
  8. Bake until the filling is just set. It will take up to 20 minutes. Think lemon meringue pie or lemon curd as this will give you an idea of the set you are looking for.
  9. Remove from the tin and allow to cool completely. Don’t panic as the whole thing sets up quite firmly when cool.
  10. Dust the whole traybake with icing sugar and sprinkle with some Maldon salt, cut into bars.
  11. Enjoy!

I have decided to enter this in the One Ingredient challenge for February as the ingredient is limes. This monthly family friendly cooking challenge is hosted by Nazima at Franglais Kitchen and Laura at How to cook good food.

      It is a pleasure, thanks for hosting. The salt on top makes the tray bake so much more margarita like.
