I don’t care how skilled is your baker, how fine are your ingredients, how competitive is your price point or how willing your customers are to pay it: if your palmier is larger than a human head, it’s too damn big.
Mine are smaller than your fist. Women look at them warily at first, but later on they always come back for seconds and assure me that size doesn’t matter.
Any woman who would look warily upon your palmiers, even temporarily, is a jaded soul with unrealistic expectations of what constitutes a satisfying pastry. The fact that you’re still willing to share just shows what a standup guy you are. :)
I know nothing of palmiers, but looking in the mirror just now, I see that I should be somewhat of an expert on the subject of oversized heads.
