I think that the point value depends on the size of the chips? As in, chip shop chips are chunky and absorb less oil, but thinner chips absorb more, making them higher in saturated fat. Someone else can probably clarify that, but if a small portion of chippy chips are 6.5 then you're probably looking at maybe a point or 1.5 points less for a cone?
Thanks Lorny for finding the post it's what i always go by that 170gs are 7.5 which i'm afraid going by my chippy is less than a cone, they say a 'normal' portion of chips is 9.5 and i think this is classed as a cone sorry if it's too late by now but if you had 14.5 left i wouldn't worry! hope you enjoyed
