Sunday Morning Appetizing Spread (New York)
If you grew up hitting the appetizing store on a Sunday morning, you know the texture of a true New York schmear. It sits high and proud on a fresh bagel, yielding instantly without tearing the soft bread. The secret behind the counter isn't an artisanal technique or an imported European curd—it's a splash of plain seltzer water. Beating cold, dense commercial cream cheese with carbonation introduces tiny pockets of gas, expanding the fat into a velvety cloud without diluting its signature tang. It is a brilliant, no-nonsense trick of the working-class immigrant kitchen.
Ingredients
- full-fat block cream cheese8 oz
- plain seltzer water2 tbsp
- scallions3 med
- kosher salt1 pinch
- cold-smoked salmon4 oz
- lemon juice1 tsp
- fresh dill1 tbsp
Method
- 01
Beat the cold cream cheese to soften the fats.
Place the block of cold cream cheese in the bowl of a stand mixer fitted with the paddle attachment. Beat on medium speed for about one minute until the cheese begins to break down from the friction, then stop and scrape down the sides of the bowl.
- 02
Whip in the seltzer water to aerate the cheese.
With the mixer running on low, pour in one tablespoon of plain seltzer. Increase the speed to medium-high and whip for one to two minutes, watching the carbonation expand the cheese. If it still looks too stiff, add the second tablespoon of seltzer and whip for 30 more seconds until the texture resembles fluffy frosting.
- 03
Fold in the mix-ins by hand.
Remove the bowl from the mixer. Using a rubber spatula, gently fold in your chosen mix-ins: either the scallions and salt, or the chopped salmon, lemon juice, and dill. Never use the mixer for this step, or you will bruise the scallions and turn the salmon into an unappetizing paste.
- 04
Serve immediately or store in the refrigerator.
The carbonated water will keep the schmear light and spreadable, even straight from the cold fridge, for up to five days.
Notes
Use full-fat block cream cheese exclusively.
Low-fat varieties lack the structural fat necessary to trap the carbon dioxide bubbles, and tub cream cheese contains stabilizers that will break down if whipped further.
Choose one flavor variation.
The ingredients list provides the components for either a sharp scallion schmear or a classic lox spread. Choose one set of mix-ins to fold into the base aerated cheese.
