Lottie Shaw's Yorkshire Parkin Biscuits x 8. We are delighted that our delicious Yorkshire Parkin Biscuits have won a Great Taste Award. To create our award winning Yorkshire Parkin Biscuits we blend together medium coarse oatmeal, black treacle, syrup, and ginger, all of which are in our Yorkshire Parkin. These ingredients create a luxury ginger biscuit that is quite unique.
