Make-Ahead Sweet and Sour Cocktail Meatballs

We wanted to do as much advance preparation as possible so the meatballs could come together in a hurry the night of a party. We needed a sweet, tangy sauce without any hints of artificial candy flavor and meatballs that wouldn’t dry out in the freezer. Here’s what we discovered:

Test Kitchen Discoveries

• Browning the meatballs in a skillet was a pain. Baking them in the oven was much faster and ensured the meatballs browned evenly.
• We found that all of the most common binders—bread crumbs, cracker crumbs, and even cornflake crumbs—dried out the meatballs. We settled on a panade, a paste made from bread softened in milk, to protect our meatballs from the dry cold of the freezer.
• Too much seasoning will overpower the meatballs, but too little will be lost in the sauce. The right balance of salt, pepper, garlic, and parsley complimented the sweet and sour flavor of the sauce perfectly.
• Tomato sauce doctored up with red pepper flakes, Dijon mustard, and a few other key ingredients took care of the sour portion of the sauce. For the sweet, we tested every type of jam and jelly we could think of and settled on one standout.
• Freezing the meatballs and sauce in separate containers eliminates almost all of the last-minute prep work. When it’s time to serve, simply reheat the sauce, dump in the frozen meatballs, and you’re done.
