Frankly I don't think you can beat a tea loaf, especially one which is Earl Grey scented. This very British bake is great for taking on picnics or in school lunch boxes and the like, it is also better after a couple of days wrapped and stored in an airtight tin.
To ensure a moist tasty cake please soak the dried fruit for at least a couple of hours in the tea so it doesn't rob the cake of its moisture whilst baking, this is particularly important if you are baking gluten free. I have been experimenting recently with mixing my own gluten free flour rather than relying on ready mixed and must say that I am impressed with the results being achieved.
Earl Grey tea dates from the 1830's and is reputed to be named after the Prime Minister of that time, a black tea with the addition of the oil of the bergamot orange.
