Abstract
Abstract Food product pieces are formed with corrugations on opposite sides thereof wherein the corrugations formed on one side have a frequency in the range from 1.5 to 5 times the frequency of the corrugations formed on the other side. As a result, flavor and texture development can be controlled during later cooking processes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
59 words
A food product comprising: a potato slice or potato dough sheet having corrugations on opposite surfaces thereof, the corrugations on one surface having a frequency in the range from 1.5 to 5 times the frequency of the corrugations on the opposite surface, and said slice or sheet having the capability of being cooked differentially in different thickness portions thereof.
Claim 2
Dependent Claim
59 words
A food product comprising: a potato slice or potato dough sheet having corrugations on opposite surfaces thereof, the corrugations on one surface having a frequency in the range from 1.5 to 5 times the frequency of the corrugations on the opposite surface, and said slice or sheet having the capability of being cooked differentially in different thickness portions thereof.
Claim 3
Dependent Claim
25 words
A food product as claimed in claim 1 wherein the corrugations on the opposite surfaces of the slice or sheet are parallel to each other.
Claim 4
Dependent Claim
31 words
A food product as claimed in claim 2 wherein the corrugations on the one surface have a frequency of about 3 times the frequency of the corrugations on the opposite surface.
Claim 5
Dependent Claim
18 words
A food product as claimed in claim 2 wherein the potato slice or potato dough sheet is fried.
Claim 6
Dependent Claim
48 words
A food product as claimed in claim 4 wherein the corrugations on the one surface have a frequency within the range from 3 to 12 corrugations per cm, and the corrugations on the opposite side have a frequency within the range from 1 to 4 corrugations per cm.
Claim 7
Dependent Claim
76 words
A food product as claimed in claim 5 wherein the amplitude of the corrugations on the one surface is within the range from 0.7 to 5.1 mm, and the amplitude of the corrugations on the opposite surface is within the range from 0.7 to 5.1 mm, and the slice or sheet has a minimum thickness between planes, defined by the deepest points of valleys of the opposite corrugations, within the range from 0.2 to 2.5 mm.
Claim 8
Dependent Claim
83 words
A food product as claimed in claim 4 wherein the potato slice or sheet, prior to frying, has corrugations on the one surface with an amplitude of about 1.5 mm, has corrugations on the opposite surface with an amplitude of about 2.3 mm, has a minimum thickness between valleys of opposite corrugations of about 1.0 mm, has a pitch on the one surface of about 4.7 corrugations per cm, and has a pitch on the opposite surface of about 1.6 corrugations per cm.
