I think I've been reading The Mid-Century Menu a little too much.
The book is Barbara Swain's Cookery for 1 or 2, published in 1978. To be fair, a lot of the recipes are pretty normal (like the mushroom rice pilaf) and are just conveniently sized down for the small household. But the chicken...
I'd seen variants on this recipe in several of the older cookbooks I have geared to the single and/or childless household. It was apparently a thing ca. 1970s to drown chicken breasts in a grape cream sauce.
Yes. I said it. Grape cream sauce. For real, drop dead, no kidding. Grape. Cream. Sauce. And it is meant to be served hot, hence the microwavable "Skater" box. Hot. Grape. Cream. Sauce.
Although I don't have a flatbed scanner and will thus make you put up with my photography, I think you should see the recipe.
To be honest, the flavor wasn't bad, either. It was more of a mouth feel and texture thing. But I ate it. Twice! So not altogether horrible. I think I'd suggest using cooked apples or something, though, if you want a hot, fruity cream sauce on your chicken.
Or just go with mushrooms. It's safer and more expected.
Fortunately, this resulted in me having some moist, lovely leftover chicken to be used in other lunches this week, because I had the good sense not to pour the cream all over all the chicken. See you tomorrow.
