On the Advantage of Syrups
I took this post down for the evening because I accidentally created some internecine warfare between a couple of my food science sources and I needed a little time to get my facts straight. Reader Bronwyn (quite helpfully I might add) challenged my early contention that hot syrup doesn’t cook egg whites in any meaningful way. Having had a little past experience taking meringue temperatures, I was sure that there was no real cooking going on. This set off a little debate on what exactly was meant by the term “cooking”, and things got confusing quickly. But anyway, here’s Michael’s original question:
READ ONI understand that when you add sugar syrup to egg whites to make Italian Merengue it cooks the whites a bit making it more stable than adding plain sugar. I’m curious if the purpose is the same when adding sugar syrup instead of plain sugar to yolks. I made a recipe for a “chocolate roll” which is to add a “light” sugar syrup to yolks and beat until light and fluffy. Then add in melted chocolate with a bit of coffee. Finally fold in stiffly beaten egg whites. Then bake and then fill the roll with whipped cream. Why would the recipe call for sugar syrup to [be beaten into] the yolks instead of plain sugar ?
