Sweetness needs acidity—and an ice wine harvested in January
There’s one question that’s debated more seriously in Canada than many political issues: Butter tarts—runny or firm? Anyone from Ontario has an opinion. Some want the filling to ooze out of the pastry shell at the first bite—warm and caramel-like, almost liquid. Others insist on a filling firm enough to hold a spoon. Both are right. Because what defines butter tarts isn’t their consistency—it’s their essence: butter, brown sugar, egg, a hint of maple syrup, all poured into a crumbly, golden-brown pastry shell and baked until caramelization begins. This isn’t a question of calories. It’s Canada on a pastry fork. The 2019 Family Reserve Cabernet Franc Icewine from Pillitteri Estate Winery responds to this sweetness not with restraint, but with depth: 208 g/l residual sugar, but 7.65 g/l acidity—a balance that can only be achieved when grapes are harvested at –8 °C and the frozen water remains inside the berry, while the must becomes concentrated like almost nothing else in the world of wine. Sweet versus sweet—and the acidity makes the difference.
Ideal wine pairing: Pillitteri Family Reserve Cabernet Franc Icewine (Niagara Peninsula, Canada)
Pillitteri Estate Winery in Niagara-on-the-Lake is one of Canada’s best-known ice wine producers—and its Family Reserve line represents the very best the winery has to offer. The vines used for this ice wine grow on sandy loam with a clay topsoil over Queenston shale; they are over 15 years old and benefit from the lake effect of Lake Ontario as well as the escarpment topography, which creates unique ripening conditions in the fall and winter.
In the glass, the wine shimmers with a delicate rosé hue. The bouquet is rich and inviting: strawberry, maraschino cherry, and raspberry jam come through first, with a hint of baking spices—cinnamon, nutmeg—and a floral note that makes the wine seem light and elegant despite its opulence. On the palate, rhubarb, red cherry, and a slightly savory spice emerge, setting the wine apart from being purely a dessert wine.
The connection to butter tarts is both logical and profound: the acidity of the Eiswein cuts through the caramel sweetness of the filling and keeps the palate alive. The raspberry and cherry notes in the wine mirror the berry flavors that emerge when brown sugar and butter begin to caramelize in the heat of the oven. And the spicy notes in the glass—cinnamon, baking spice—echo exactly what’s happening inside the pastry shell. This is no coincidence. It’s a pairing where both sides come out on top.
The recipe:

Canadian Butter Tarts
Equipment
- 1 Muffinform (12er)
- 1 Runde Ausstechform (Ø 10–11 cm)
- 1 Nudelholz
- 1 Kleiner Topf für die Füllung
- 1 Schneidebrett und scharfes Messer
Ingredients
FOR THE SHORTCRUST PASTRY:
- 250 g Flour
- 125 g cold butter diced
- 1 tablespoons of sugar
- ½ teaspoon of salt
- 5 –6 tablespoons of ice-cold water
FOR THE FILLING:
- 100 g Butter
- 200 g brown sugar dark
- 2 Eggs whisked
- 2 teaspoon of maple syrup dark, Grade A
- 1 TL vanilla extract
- 1 A pinch of salt
- 100 g Pecans coarsely chopped
Instructions
MAKING THE DOUGH:
- Mix the flour, sugar, and salt.
- Work in the cold butter until the mixture is crumbly.
- Gradually stir in ice-cold water, one tablespoon at a time, until the dough just holds together.
- Flatten it, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
PREPARE THE FILLING:
- Melt the butter in a small saucepan over medium heat.
- Stir in the brown sugar until it has dissolved—do not let it boil.
- Remove from the stove and let cool slightly (about 5 minutes).
- Stir in the eggs, maple syrup, vanilla, and salt—mix until smooth and even.
SHAPING AND BAKING TART:
- Preheat the oven to 200 °C using top and bottom heat.
- Roll out the dough thinly (about 3 mm) on a floured surface.
- Cut out round discs (Ø 10–11 cm) and gently press them into the muffin cups.
- Spread the pecans evenly over the pastry shells.
- Pour the filling over the top—fill each cavity about ¾ full, not to the brim.
- Bake for 12–15 minutes, until the filling has risen slightly and is golden brown.
- Important: The filling will continue to set as it cools—remove it from the oven while it’s still slightly wobbly.
- Let it cool in the pan for 10 minutes, then carefully remove it.
SIDE DISHES:
- Lightly salted whipped cream
- Fresh raspberries or strawberries
- Fleur de sel to finish
