Help me salvage my Swiss Buttercream?
I was trying to make a Swiss buttercream and ran into trouble. For a play-by-play, read below. To cut to the chase, skip to the end.
Here's what I did:
Put 4 egg whites (from the fridge) and 1 c sugar in a double boiler and got it nice and warm/hot. I picked out a few bits that got too hot on the sides (cooked egg white! I'm baking at my sister-in-law's so I don't have my thermometer.)
Used a hand mixer to beat 'em up! I couldn't get them beyond a "heavy ribbon" stage. The mixture would level out in the bowl within 8 seconds, no matter how long I beat them. Seriously folks, I'm talking easily 45 minutes of beating with a mediocre hand mixer. I tried the whip beater, the batter beaters, whipping by hand... they would not budge.
After reading replies to some similar issues here, I thought maybe the trouble was too much sugar:egg whites. So I thought I'd try adding more egg whites...
Two more egg whites (again, from the fridge) in the double boiler, mixed in some of the marshmallowy batter. (Spoiler alert: Don't do this! It resulted in a white, gummy substance which I over-cooked, in part because I had a hard time estimating when it reached pasturization. Pitched it and started again.)
Two egg whites, maybe a teaspoon of sugar. (I thought maybe the bit of sugar would help when incorporating the new stuff into the marshmallowy bowl?) After pasteurizing, I beat the 2 egg whites (including the bit of dissolved sugar) to stiff peaks. (This looked much more like stiff egg whites than a glossy meringue --just to say I truly didn't add much sugar.)
Plopped the stiff egg whites into the marshmallowy bowl. Sorta folded it in until mostly incorporated which left me with a no-longer-ribbon-stage bowl of fluffy white goo. Used the hand mixer with beaters and over about 10 minutes of whipping, reached glossy, soft peaks. Another 10-15 minutes of beating didn't get me anywhere. :(
So I figured soft peaks would have to do. (I didn't dare use more off the sister-in-law's eggs!) I began to add soft slices of room-temperature butter. After 2-3 tablespoons, I added 3-4 tablespoons of whipped, room temperature cream cheese. Gradually added more butter, more cream cheese....and the egg whites seemed to deflate a bit. It won't set up. It's fluffy, but runny. Let's call it a "thin-ribbon" stage. Even after refrigerating overnight, it's not stiff.
At this point, here's what's in the bowl:
6 egg whites
1 C +2t(ish) sugar
5(ish) T salted butter
8 oz cream cheese
What went wrong and how do I salvage this? I have two young nephews eager to frost cupcakes so they can sing me happy birthday :)
