It's more than a case of chefs adding their personal touch to recipes. It also depends largely on which culture - for many across the globe serve some sort of meatball - they draw their inspiration from.
The meat? Anything from turkey to tofu. The binder? Pureed rice, breadcrumbs, cheese, pulpy potatoes, an egg or two, and cream all can do the trick. Cooking? Fry, bake, braise. Maybe, a combination.
"It's all about personal taste," said Koren Grieveson of Avec restaurant in Chicago. "There is no secret science."
That's good news, because if there's no right way to do it, it's probably harder to mess up.
Still, we were confident there must be ways to improve meatballs, regardless of variety. These are the tips we gathered from the pros.
- Ask the butcher for scraps
Meatballs are not the vehicle for expensive tenderloin and sirloin. Meatballs were created as a way of using scraps, so start there, says Daniel Holzman, chef and owner of The Meatball Shop in New York. Diverse cuts of meat add depth of flavor.
"We use a lot of prosciutto scraps," said Liza Shaw, executive chef and owner of A16 restaurant in San Francisco. "There comes a point when you can no longer slice a leg of prosciutto."
So get to know the butcher. They have stuff they don't sell, from unusable shavings of meat to throwaway ends of ham. Grind it all in a blender or food processor, then add it to your meatball mix.
- Sausage meat
A quick way to skip the hassle of mixing meat is to take a links of your favorite sausage and cut away the casing, Grieveson said. Mix the meat with breadcrumbs, spices, etc. "Most sausages already have the required amount of fat," she said.
- Fat doesn't have to come from meat
There is plenty of debate on what the right fat content of a meatball should be, though most people put it in the 20 to 40 percent range. But that doesn't mean the fat must only come from the ground meat, says former Top Chef candidate Tim Love of Dallas.
If the meat is the flavor, the fat is what protects that flavor, stroking each ground morsel with moistness while it cooks, he said.
Butter, cream or cheese are all good additions. Harder and stringier cheeses - including cheddar, mozzarella and Parmesan - are good bets. A soft goat cheese will likely cause the meatball to fall apart.
- Liquid also is important
Add water, says Joey Campanaro of Little Owl restaurant in New York. "The mixture should be wetter than you imagined," he said. "That keeps the meatballs moist. When you think about it, it's the very same concept as soup dumplings. It emulsifies the fat as you fry it. The meatballs stay moist. Without the water, the fat is going to go right into the sauce. You are going to have a greasy sauce and a dry meatball."
- Save old bread
"If you liked it when it was fresh, you are going to like it a day later or when it is frozen," Shaw said.
Toast the moisture out of the bread without burning it, then run it through a food processor or crush by hand. When combined with liquid, bread serves as a binder for the meatball. It also helps to retain moisture.
- Use a light hand when mixing
Anytime you make something with bread, there is a fear of over mixing, Shaw said. "Mix it just enough but not too much," she says. "If you knead it too much you are going to get a tough texture." To be safe the Shaw recommends mixing the wet ingredients and meat mixture separately, then combining the two.
- Size matters
The larger the meatball, the more the more work it takes keeping it together, Campanaro says. The outside also can overcook before the inside is done. About 1 1/2 inches - or the size of a golf ball - is a good size, he says. This also prevents them from falling apart while being eaten.
- Always make a tester
"You always have to make a tester meatball," Holzman says. "Making meatballs is like baking. What you get at the end you can't really change." Before making them all, cook one and taste it. If it falls apart, add more of a binder. If it's too dense, add more liquid. This is also where you can adjust the seasoning, he says. "If it needs more salt, don't be afraid to put more in."
- Moisture depends on cooking method
If you are roasting or frying meatballs, you would want a wetter meatball to keep the moisture from being sucked out, as the heat extracts liquid, Shaw said. If you are braising the meatball in red sauce, use less liquid. Cooking in the sauce will continue to baste the meatball, keeping it moist and from falling apart. If braising a meatball, taste it every 30 minutes. If it's tough, don't fret, Shaw says, braising it longer will fix the problem.
- Time adds flavor
Letting a braise sit overnight allows the meat to take on more flavor, Shaw says. "Everything that is braised benefits from a day to sit. It sits in the fridge and the next day, it is intensified."
