Execution Methodology & Culinary Technique

1. 1

   Make the Pastry and Chill It

   35 Minutes Room temperature, about 21°C (70°F)

   Rub the cold butter into the flour, sugar and salt until the mix looks like breadcrumbs, then stir in the beaten egg and just enough cold water to bring it together into a dough. Flatten into a disc, wrap, and chill for 30 minutes.

   Handle the dough as little as possible — overworking it makes the pastry tough. If the dough feels sticky, chill it for 10 minutes more before rolling.

   Done when: The dough is smooth, firm and cold, and holds together without cracking.

2. 2

   Beat the Frangipane

   10 Minutes Room temperature, about 21°C (70°F)

   Beat the softened butter and sugar until pale and fluffy, then beat in the egg, and fold in the ground almonds until you have a soft, spreadable cream.

   Beat the butter and sugar well — the air in the frangipane is what makes it rise and puff around the plums.

   Done when: The frangipane is pale, fluffy and smooth, with no lumps of butter left.

3. 3

   Prepare the Plums and Crumble

   10 Minutes Room temperature, about 21°C (70°F)

   Toss the halved plums with the sugar and lemon zest. In a separate bowl, rub the cold butter into the flour, sugar and cinnamon until the mix forms pea-sized crumbs.

   Pat the plums dry before sugaring them — wet plums make the frangipane soggy. Leave the crumble in the fridge until you need it so it stays crisp.

   Done when: The plums are glossy with sugar and the crumble is loose and crumbly, not pasty.

4. 4

   Line the Tin and Fill

   5 Minutes Room temperature, about 21°C (70°F)

   Preheat the oven to 180°C (350°F). Roll the chilled pastry out and line a 23 cm tart tin, trimming the edges. Spread the frangipane over the base, arrange the plum halves cut-side up in overlapping rings, and scatter the crumble over the top.

   Press the pastry gently into the corners of the tin and prick the base with a fork so it does not puff up. Leave a small rim of pastry above the filling — the frangipane rises as it bakes.

   Done when: The tin is evenly lined, the frangipane is smooth, and the plums sit in neat overlapping rings under the crumble.

5. 5

   Bake Until Golden

   40 Minutes 180°C (350°F)

   Bake the tart on the middle shelf for 40 minutes, until the crumble is deep golden, the plums are soft and jammy, and the frangipane is set and puffed at the edges.

   If the crumble browns too fast, cover the tart loosely with foil for the last 10 minutes. The frangipane is set when it no longer wobbles in the middle.

   Done when: The crumble is deep golden, the plum juices bubble at the edges, and a skewer in the frangipane comes out clean.

6. 6

   Cool and Slice

   10 Minutes Room temperature, about 21°C (70°F)

   Cool the tart in the tin for 10 minutes, then lift it out onto a rack and leave it until just warm. Slice with a sharp, thin knife and serve with whipped cream or ice cream.

   Cutting while it is piping hot makes the slices fall apart; 10 minutes in the tin is enough for the frangipane to firm up.

   Done when: The slices hold their shape, with crisp pastry, soft frangipane and jammy plums in every piece.

Who Should Eat It

Who Should Eat

• General adultsA rich bakery tart — one slice with coffee and a little cream makes a proper Belgian afternoon treat.
• ChildrenChildren usually love the jammy plums and crumble — serve a small slice, warm but not hot, with ice cream.
• ElderlySoft and easy to chew once cooled slightly — serve a small slice at room temperature with whipped cream.
• Pregnant womenSafe when the tart is baked right through and the frangipane is fully set — eat it freshly baked and warm, and keep to one slice.
• Breastfeeding womenA filling, energy-rich snack; the plums add vitamin C and fibre, so enjoy one slice as part of a varied diet.
• AthletesAbout 63.9 g of carbohydrate per slice makes this a good energy top-up after training — eat it with a glass of milk for protein.
• Weight gainAdd a second small slice and a scoop of ice cream to lift the energy of the snack.
• Weight lossThe tart is rich and sweet, so keep to one small slice, skip the ice cream, and serve it with black coffee instead.

Health Conditions — Adjust or Avoid

Conditions

• DiabetesOne slice carries about 63.9 g of carbohydrate, mostly from sugar and pastry, so keep to a small slice and skip sweetened cream; ask your clinician about portions.
• High blood pressureAbout 119 mg of sodium per slice is low, but the sugar is high — keep to one slice and serve it with black coffee; ask your clinician about your sodium target.
• Kidney diseaseModerate in protein and low in sodium, but the sugar is high, so it may not suit a restricted kidney diet; ask your clinician before eating it.
• GoutPlums and almonds are low in purines, so a small slice is usually fine — keep the portion small during a flare; ask your clinician for advice.
• Stomach issuesThe buttery pastry and sweet plums can sit heavily on a sensitive stomach — eat a small slice, chew well, and skip the cream if it troubles you; ask your clinician if symptoms flare.
• Cardiovascular diseaseThe butter, sugar and pastry make this tart rich in saturated fat and sugar, so keep to one small slice and balance it with plain fruit; ask your clinician about portions.
• Fatty liverThe butter and sugar add up, so keep the portion to one small slice and serve it with black coffee instead of ice cream; ask your clinician about portions.
• Food allergiesContains wheat (pastry and crumble), milk (butter), egg and tree nuts (almonds). Check the flour label for other allergens if you are unsure; ask your clinician if you are unsure.
• Special therapeutic dietsRich, sweet and made with white pastry — it can be adapted with less sugar and a smaller slice, but ask your clinician or dietitian before relying on it for a therapeutic diet.

If you have a medical condition, consult your doctor before changing your diet.
