I want to make some heart shaped biscuits (ala NIgella in feast) for my DH for valentines day (awww). But the recipe calls for vegetable shortening which I don't have and don't want to use anyway because of all the trans fats.
Can I replace it with butter - and if so, is it a like for like replacement and do I need to add more flour to compensate for increased liquid from butter?
Thanks
