Renata, traditionally we don't use dates in a tea-brack - but you can put whatever fruit you like into it.
Here's the recipe:
RITA'S IRISH TEA BRACK
16oz dried fruit (we just use raisins and sultanas)
16 fl oz strong black tea
4 oz soft brown sugar
4 oz granulated white sugar
1 egg
14 oz plain white flour (without raising agent)
1 heaped teaspoon mixed spice
1 teaspoon baking powder
Put the raisins and sultanas into a bowl, cover with the tea and leave overnight to allow the fruit to plump up. The next day preheat the oven to 160C/320F. Line two 2lb loaf tins with baking parchment. Add the sugar and egg to the fruit and tea and combine well. Sieve the flour, mixed spice and baking powder and add it to the fruit mix stirring thoroughly. The mixture should be softish. You can add a little more flour if it seems too runny or a little more tea, or milk, if it seems to dry. Divide the mixture between the two loaf tins. Bake at 160C/320F for 30 minutes and then turn down the oven to 150C/300F for a further 20 minutes or until a skewer comes out clean. Cool on a wire rack - if you can wait that long - and serve with butter and a cup of tea. Enjoy.
I have a recipe for Barmbrack similar to this but it includes currents and only brown sugar, not the mix of sugars and for a shortcut - if I have forgotten to put the fruit to soak overnight (usual occurance
) I will use hot tea and simmer the fruit for about 1/2 hour - just be careful that the mix is not too hot when adding the egg!
