PROCESS OF PRODUCHQG A FILLED A number of factors in?uence the frying operation, DOUGHNUT such as the composition of the dough or the temperature Howard B.

No. 140,247 from about one minute to three minutes. However, the 1 Claim. (Cl. 99-86) preferred period of frying is from one and a half to two minutes. This invention relates to an improved fried product, 10 The frying medium to be employed in the practice of and more particularly concerns a ?lled fried product such the invention ‘may be any suitable frying oil, fat or grease, as a ?lled doughnut or a ?lled fried pie. hydrogenated oils being preferred in the present invention. Filled doughnuts are well known in the art. They are The following examples are illustrative of the practice generally made from yeast-raised doughs that have been of the invention and are not intended to be restrictive of fried in oil, grease or fat for a suitable period of time. 15 the scope or practice of the invention. The ?lling operation is performed in a separate step after the doughnuts have been fried by individually injecting Example 1 them with the desired filling. This requirement for a sep A ‘cake doughnut batter of the same composition as‘ arate ?lling step is costly and time consuming. Up to 20 the previously described cake dough formula is placed now, there has been no attempt to ?ll the doughnut be in a doughnut machine having an annular die opening fore it is fried.
