Cream the butter with the sugar. Add the egg and beat some more.
Add the salt, zest, cardamom and 1 tsp of lemon juice. Beat. Add the flour in batches and beat until you have a nice dough.
Take half of the dough and add the matcha tea and the rest of the juice. Beat to get the green dough. Put both in a container, cover well and put in the fridge for at least an hour.
Place the dough between two sheets of wax paper. It will be easier to roll out.
Roll it out until it is about 5mm thick. Cut shapes and place them on a cookie sheet. This dough will not lose its shape so it’s perfect for making different shapes
Put in a preheated oven, 180C, for about 8 minutes (depends on how big/thick your cookies are). They should not brown.
Take them out of the oven and let them cool. You can let them as they are or you can decorate them. Here I decorated them with royal icing.
