Jam Macarons: Crisp Shells, Soft Centers

Jam macarons are delicate French-style almond meringue cookies sandwiched around a small spoonful of fruit preserves. Their crisp shells and chewy centers pair well with the bright sweetness of jam; a measured batter, properly dried shells, and a modest filling help them bake evenly and stay neat.

Ingredients

1 cup (100 g) fine almond flour
1 cup (100 g) powdered sugar
2 large egg whites, about ¼ cup (60 g), at room temperature
¼ cup (50 g) granulated sugar
⅛ teaspoon (0.5 ml) cream of tartar
¼ teaspoon (1 ml) vanilla extract, optional
Gel food coloring, optional; use a small amount
⅓ cup (110 g) thick seedless jam, such as raspberry, strawberry, or apricot

Instructions

Prepare the trays and dry ingredients. Line two baking sheets with parchment paper or silicone baking mats. If you have a macaron template, slide it under the parchment and remove it before baking. Sift the almond flour and powdered sugar together into a bowl, pressing larger pieces through the sieve; discard any stubborn coarse bits rather than forcing them through. This fine mixture helps the shells bake smooth.
Whip the meringue. Make sure the mixing bowl and beaters are clean and free of grease. Beat the egg whites with the cream of tartar at medium speed until foamy. Add the granulated sugar gradually, then beat at medium-high speed until the meringue is glossy and forms stiff peaks. When you lift the beater, the peak should hold with only a slight bend. Beat in the vanilla and a tiny amount of gel color, if using. Avoid liquid coloring, which can loosen the mixture.
Fold the batter. Add the sifted almond mixture to the meringue in two additions. Fold with a flexible spatula, scraping around the bowl and through the center. As the batter loosens, use a little more pressure to deflate some air. Stop when it flows slowly in a thick ribbon and a ribbon drawn across the surface settles back in about 10–20 seconds. Batter that is too stiff makes peaked shells; batter that is too runny spreads into flat rounds.
Pipe the shells. Transfer the batter to a piping bag fitted with a ½-inch (1.25 cm) round tip. Pipe 1½-inch (4 cm) rounds onto the prepared trays, leaving about 1 inch (2.5 cm) between them. Hold the bag vertically and lift straight up at the end of each round. Tap each tray firmly on the counter several times to release air bubbles. Pop any visible bubbles with a toothpick.
Let the shells rest. Leave the piped rounds uncovered at room temperature for 30–60 minutes, until the tops feel dry and do not stick to a lightly touched fingertip. Humidity affects the timing, so use the touch test rather than the clock alone. During this rest, heat the oven to 300°F (150°C), using conventional heat if possible, and position a rack in the center.
Bake one tray at a time. Bake for 14 minutes, rotating the tray once after about 7 minutes if your oven has hot spots. The shells are ready when they have formed ruffled feet and do not wobble when gently nudged. Let them cool completely on the tray, about 20 minutes, before peeling them away. If they stick, they may need another minute or two in the oven next time; do not pull warm shells from the parchment.
Fill and mature. Pair shells of similar size. Spoon or pipe about ½ teaspoon (2.5 ml) of thick jam onto the flat side of half the shells, keeping it away from the edges, then sandwich with the remaining shells using gentle pressure. Refrigerate in a covered container for 24 hours so the filling softens the centers and the flavors meld. Bring to room temperature before serving.

Tips

Weigh the ingredients when possible. Macaron batter is sensitive to small measurement differences. If measuring by cups, spoon the almond flour and powdered sugar into the cups and level them; do not pack them.
Use thick jam. A runny preserve can leak out and make the shells soggy. If your jam is loose, simmer it briefly in a small pan until thickened, then cool it fully before filling. Do not add warm jam to the cookies.
Adjust for your room. Shells may take longer than an hour to dry on a humid day. If they still feel tacky, wait longer rather than baking them early. A fan can help circulate air, but do not aim strong airflow directly at the trays.
Check your oven. An oven thermometer can reveal temperature swings. If shells brown or crack, the oven may be too hot, the batter may be overmixed, or the shells may not have rested long enough.

Serving Suggestions

Serve the macarons at room temperature, when their centers are soft and their flavor is easiest to appreciate. Arrange them on a dessert plate with tea or coffee, or offer a few alongside fresh berries and a simple cake. Because they are sweet and rich, small portions make a satisfying finish to a meal. For a tidy dessert platter, group colors and fillings separately and add the cookies shortly before serving.

Variations

Choose a jam that is smooth and thick enough to stay between the shells. Raspberry and strawberry bring familiar berry flavor; apricot gives a mellow, tangy filling, while blackcurrant or cherry makes a more assertive version. If using jam with seeds, strain it for a smooth center or leave the seeds in for texture. Keep the filling restrained: too much jam pushes the shells apart.

For a chocolate-and-berry pairing, add 1 tablespoon (5 g) unsweetened cocoa powder to the sifted dry ingredients, replacing the same amount of almond flour, and use raspberry jam. The cocoa can make the batter slightly drier, so watch the texture as you fold. For citrus, mix a little finely grated lemon zest into the jam. Gel color is optional; leave the shells plain if you prefer, since color does not affect the flavor.

Storage and Reheating

Keep filled macarons in an airtight container in the refrigerator for up to 4 days. Refrigerate them within 2 hours of filling, and do not leave them at room temperature for more than 2 hours. Before serving, let them sit at room temperature for about 20–30 minutes for the best texture. Macarons are not reheated.

For longer storage, freeze filled macarons in a well-sealed container for up to 1 month, with parchment between layers to protect the shells. Thaw them overnight in the refrigerator, then bring them to room temperature while still covered to reduce condensation. Unfilled shells can also be frozen in an airtight container for up to 1 month; thaw before adding jam.

Frequently Asked Questions

Why did my macaron shells crack?
Common causes include batter that was not folded enough, air bubbles left in the piped rounds, an oven that runs hot, or shells baked before their surfaces dried. Tap the trays, pop bubbles, use an oven thermometer, and wait until the tops feel dry before baking.

Do I need to age the egg whites?
No. Room-temperature egg whites whip readily, and this recipe does not require aging them. Separate eggs carefully so no yolk enters the whites, and bring the measured whites to room temperature before whipping.

Can I use regular food coloring?
Gel coloring is preferable because it adds strong color with little liquid. Liquid coloring can thin the meringue and affect the batter, so omit it if gel coloring is unavailable rather than adding a large amount.

Can I make the shells ahead?
Yes. Cool the shells completely, then store them unfilled in an airtight container at room temperature for up to 2 days, or freeze them for up to 1 month. Fill with jam and refrigerate for the 24-hour maturation before serving.

Why are the shells hollow or chewy?
Hollows can result from under-whipped meringue, uneven oven heat, or shells that are underbaked. Chewy centers are normal after filling and maturation; if the shells themselves remain soft before filling, bake them a little longer and let them cool fully.

Can I use homemade jam?
Yes, provided it is thick and completely cool. Homemade jam varies in moisture, so cook it down if it runs off a spoon. Use it as a refrigerated filling and follow the same storage limit as the finished macarons.
