Full Ingredients

For the Ostkaka

• 2 liters whole milk (8 1/2 cups), 3.5% fat
• 30 g all-purpose flour (1/4 cup)
• 1/2 tsp liquid rennet, diluted in 2 tbsp cold water (use label’s guidance; 1/2 tsp is typical for 2 L milk)
• 3 large eggs
• 100 g granulated sugar (1/2 cup)
• 240 ml heavy cream (1 cup)
• 60 g blanched almonds, coarsely chopped (1/2 cup)
• 1/4 tsp almond extract
• 1/4 tsp fine sea salt
• 1 tbsp unsalted butter, for greasing the dish

For Serving

• 240 ml heavy cream (1 cup), lightly whipped (unsweetened or with 1–2 tsp sugar)
• 240 ml lingonberry jam (1 cup), or tart raspberry/red currant jam

Optional Traditional Touch

• 1 tiny bitter almond, finely grated, or 1/8 tsp bitter almond extract (use sparingly; see note in Pro Tips)

Step-by-Step Instructions

Step 1: Set up and warm the milk

Add 1 cup (240 ml) of the cold milk to a large, nonreactive pot. Whisk in the flour until smooth with no lumps, then whisk in the remaining milk. Warm gently over low heat, stirring occasionally, until the milk reaches 37°C/98.6°F (body temperature). Do not overheat; the milk should feel just warm to the touch.

Step 2: Add rennet and let the curd form

Remove the pot from heat. Stir the diluted rennet into the warm milk for about 5 seconds with an up-and-down motion. Immediately cover and let stand undisturbed for 45 minutes in a draft-free spot until you have a delicate, custard-like gel.

Step 3: Cut and drain the curd

Using a long knife or spatula, cut the curd into roughly 2 cm (3/4 in) cubes. Let rest 10 minutes to release whey. Using a slotted spoon, gently transfer curds to a fine-mesh sieve or a cheesecloth-lined colander set over a bowl. Drain for 15 minutes. Reserve 120–240 ml (1/2–1 cup) of the whey to adjust batter consistency later. The curds should remain very moist and tender.

Step 4: Prepare the custard base

Heat the oven to 175°C/350°F. Grease a 20×30 cm (8×12 in) baking dish or a 23 cm (9 in) round ceramic dish with the butter. In a mixing bowl, whisk the eggs, sugar, and salt until combined and slightly lightened, 30–45 seconds. Whisk in the cream and almond extract. Stir in the chopped almonds (and bitter almond extract if using).

Step 5: Combine curds and custard

Gently fold the drained curds into the custard. If the mixture looks very thick, stir in 1–3 tablespoons of reserved whey until it is thickly pourable—like a loose rice pudding. Pour into the prepared dish and smooth the top.

Step 6: Bake until just set

Bake on the center rack for 45–55 minutes, until edges are lightly golden and the center has a soft, even wobble (no liquid slosh). An instant-read thermometer inserted in the center should read 80–82°C (176–180°F). Do not overbake—tender is the goal.

Step 7: Finish and serve lukewarm

Let the ostkaka rest 20–30 minutes so it settles and slices cleanly while still lukewarm. Lightly whip the cream to soft peaks. Warm the jam with 1–2 teaspoons water until spoonable. Serve the ostkaka in spoonfuls or wedges with a dollop of whipped cream and a spoon of tart jam. It should be creamy inside with a gentle almond aroma.

Pro Tips

• Milk temperature matters: Rennet works best around 37°C/98.6°F. Too hot will inhibit setting; too cool slows it down.
• Handle curds gently: Keep the curds moist; squeezing them dry makes a crumbly cake. Reserve whey to fine-tune the batter texture.
• Bake to a wobble: Pull the ostkaka when it quivers uniformly. Overbaking leads to a dry, eggy texture.
• Almond aroma: Classic versions sometimes include bitter almond. If using, keep it tiny—1/8 tsp extract or one small bitter almond finely grated adds plenty. Omit for children or if unsure of source.
• Serve lukewarm: This dessert shines when warm, not hot; flavors and custard texture are best after a 20–30 minute rest.

Variations

• Everyday cottage-cheese version: Swap the curd-making step with 500 g cottage cheese (about 2 cups), well-drained. Mix with 3 eggs, 80–100 g sugar, 180 ml cream, 2 tbsp flour, 60 g chopped almonds, 1/4 tsp almond extract, and a pinch of salt. Bake at 175°C/350°F for 35–45 minutes.
• Gluten-free: Replace flour with 2 tbsp potato starch or fine white rice flour in both the milk slurry and the cottage-cheese variation.
• Individual portions: Bake in 8 buttered ramekins (175 ml/6 oz each) for 25–30 minutes. Perfect for dinner parties and easy reheating.

Storage & Make-Ahead

Refrigerate leftovers, covered, for up to 3 days. Rewarm gently at 150°C/300°F for 12–15 minutes until just warm, or microwave individual portions at low power. You can make the curds up to 12 hours ahead; keep refrigerated and fold into the custard just before baking. Freezing is possible for up to 1 month; thaw overnight and rewarm gently, noting texture may become slightly drier.
