Percy resisted the urge to shake his head, that would be be far too rude, and instead readjusted his glasses higher on his nose. "I'm afraid that is exactly what you will end up with, even if you purchased full-fat milk." Since she had invited him to give her his assistance, Percy more thoroughly examined the recipe. What she was actually looking for was heavy whipping cream. Which came in much smaller packages than jugs.
"It is nice to meet you, Prue." Juggling his own basket, Percy took her hand and gave her a perfunctory shake. "Percy."
While she had made an assessment of him, Percy had done no such thing. He could only see someone who had asked him for his help and while he no longer pontificated at the slightest opportunity, he was always happy to show and share a bit of knowledge that he possessed. He lead her back over back to the dairy aisle and swapped her 1% milk for the correct heavy whipping cream. "You will want to add the egg yolk, sugar, and cream together and simmer. Do not bring it to a boil or it will not thicken correctly."
