Make the filling
Put the jam in a bowl and stir to loosen. Add the raspberries and lightly crush with the back of a fork.
Make the cake
Position a rack in the bottom third of the oven and heat the oven to 350°F.
Spread the almonds on a rimmed baking sheet and toast, stirring once or twice, until golden, about 7 minutes. (Leave the oven on.) Cool the almonds to room temperature. Reserve 1-1/2 Tbs. of the almonds for the garnish and pulse the remaining nuts in a food processor until finely ground.
In a large bowl, combine the ground nuts with the baking powder and reserve.
Butter an 18x13-inch rimmed baking sheet. Line the pan with parchment. Butter the parchment and sprinkle the flour over it, shaking the pan for even coverage and knocking out the excess.
In a stand mixer fitted with the whisk attachment, beat the egg yolks, granulated sugar, and almond extract on medium-low speed until combined. Increase the heat to medium high and beat until light and fluffy, about 3 minutes. Fold into the ground nuts until incorporated.
In a clean bowl with a clean whisk, beat the egg whites and salt on medium-high speed until medium peaks form. Fold one-third of the beaten whites into the almond mixture to lighten it. Gently fold in the remaining whites until the batter is evenly colored, with no streaks of white. Transfer the batter to the prepared pan, gently spreading it with an offset spatula.
Bake, rotating the pan halfway through, until golden-brown, set to the touch, and beginning to pull away from the sides of the pan, 18 to 20 minutes. Immediately loosen the cake from the sides of the pan with a paring knife. Sift the confectioners’ sugar evenly over the cake
While the cake is still hot, lay a clean, unscented, lint-free kitchen towel over it. If the towel is long, extend one end about 1-1/2 inches beyond a short side of the cake and don’t worry about the other end. Invert a large rack or cutting board over the towel. Holding both the baking sheet and the rack with protected hands, invert the cake. Remove the baking sheet and parchment.
Using both hands and starting from the short end with the shortest towel overhang, roll the cake and the towel up together. Let cool for 30 minutes.
Carefully unroll the cake; it should look wavy and both ends should curl. (It’s OK if there are some small cracks.) Let cool completely, 10 to 15 minutes.
Using an offset spatula, spread the filling over the cake to within 1-1/2 inches of the far short edge and to within 1/2 inch of the other edges. Be sure to coax the filling into the interior of the closer curled end so that when the cake is sliced there will be filling in the center of the spiral.
Reroll the cake without the towel this time. The filling may squish out of the ends a bit, which is fine.
Finish the cake
With a serrated knife and a sawing motion, trim the ends of the cake. Using 2 large spatulas, transfer the cake to a serving platter.
Chill a metal bowl and the beaters of an electric mixer or a whisk. Beat the cream and granulated sugar to medium peaks. Spoon dollops of whipped cream on top of the roulade. Scatter the reserved almonds over the cream and garnish with the raspberries. Slice with the serrated knife and serve.
