Are they "Harrods Chocolate Chunk Biscuits" ? I googled and googled all forms of harrods chocolate chip cookie recipe - before going to harrods website and looking at what food items they have.. and then I googled all forms of Harrods Chocolate Chunk Biscuits.. with no luck either. recipesource.com (one of thee largest recipe inventories online) only has 2 harrods recipes and not the one you are looking for. Sorry.. it doesn't look like it is out there. I would suggest either buying a tin (harrods.com - food and wine - pantry) .. it looks like they will ship to the US, and they will deduct the VAT (nice!) they are L 4.21 - alternatively try emailing them and asking for the recipe. (If they send it though, it would be nice of you to post it on recipesource to share with all!)
