“Is that a custard or a meringue?”/“You’re not wrong. It’s a custard.”

A joke about the Scottish accent is:
 
SCOTSMAN (at a bakery): Is that a custard or a meringue?
ENGLISHMAN: You’re not wrong. It’s a custard.
 
“Or a meringue?” sounds like “Or am I wrong?” The joke was posted on the newsgroup alt.fan.eddings on July 3, 1998.
 
 
Wikipedia: Meringue
Meringue (/məˈræŋ/, mə-RANG; French pronunciation: ​[məʁɛ̃ɡ]) is a type of dessert, often associated with French, Swiss, and Italian cuisine, traditionally made from whipped egg whites and sugar, and occasionally an acidic ingredient such as lemon, vinegar or cream of tartar. A binding agent such as salt, cornstarch or gelatin may also be added to the eggs. The addition of powdered sugar, which usually contains corn starch, to the uncooked meringue produces a pavlova. The key to the formation of a good meringue is the formation of stiff peaks by denaturing the protein ovalbumin (a protein in the egg whites) via mechanical shear. Meringues are often flavoured with vanilla, a small amount of almond, or coconut, although if extracts of these are used and are based on an oil infusion, an excess of fat from the oil may inhibit the egg whites from forming a foam.

Imagine it being said in a Scottish accent.
Is that a donut, or a meringue?
Is that a donut or am I wrang (wrong) ?
 
So the response is basically saying, no, you’re not wrong, it is a donut.

Scotsman: “Is that a doughnut that you’re eating or a meringue?”
Englishman: “No, you’re not wrong… it is a doughnut!”

Is that a cake in the window or a meringue ?
Yes it is a cake, you’re not wrong…
     
16 August 2007, Daily Mail (London, UK), “Prevented from returning to his” by Ephraim Hardcastle, pg. 1:
I’m reminded of the Scottish lady out on a similar quest who (in her exquisite Edinburgh accent) inquires of the baker: ‘Is this an eclair or a meringue?’ Baker: ‘You’re not wrong, ma’am. It’s an eclair.’
