Method
Press shortcrust-pastry evenly into a buttered 24cm tart tin, working from the center outward. Chill 15 minutes in the freezer to firm the fat.
Prick the base 15-20 times with a fork. Line with crumpled parchment and fill with pie weights or dried beans.
Pour through a fine mesh strainer into a jug, pressing with a spatula to remove any fibrous bits.
Set the cooled tart shell on the center oven rack. Pour squash custard in a single smooth motion until 3mm from the rim.
Bake at 170C for 22-25 minutes. The filling should tremble like set gelatin when the tin is nudged — a thermometer reads 82C at the center. If it ripples like liquid, bake 3-4 minutes more.
Cool at room temperature 20 minutes, then refrigerate 30 minutes until the custard is fully firm and pulling slightly from the tin edges.
Remove from heat. Add cold butter cubes one at a time, stirring gently after each until incorporated. Continue stirring until glossy and fluid, about 72C on a probe thermometer.
Pour glaze over the chilled tart in one pour from the center. Let it flow naturally to the edges — do not spread. Cool at room temperature 10 minutes, then refrigerate 20 minutes to set the glaze to a firm, shatter-resistant finish.

Safety & Storage
Cooking Temperature
Custard must reach 82C at the center before removal from oven. Undercooked eggs pose Salmonella risk—use a probe thermometer and verify firm set gelatin consistency before cooling.
Cross Contamination
Do not use the blender jar for custard if it previously processed allergens. Wash thoroughly with hot soapy water between uses, or designate allergen-specific equipment.
Butter used for greasing the tart tin should not contact allergen-free surfaces. Use dedicated greasing tools or disposable brushes for strict allergen control.
Storage
Refrigerate completed tart within 2 hours of cooling. Contains dairy (heavy cream, butter) and eggs—perishable custard desserts require consistent refrigeration below 4C.
Shelf Life
Consume within 3-4 days for optimal quality. Beyond this window, dairy custard may spoil even under refrigeration due to moisture content and pH.
Handling
When tempering cold butter into chocolate glaze, add pieces gradually and stir gently. Rapid addition causes seizing and ruins texture.
High Risk Population
Young children, elderly, pregnant individuals, and immunocompromised persons are at elevated risk from undercooked egg custard. Ensure 82C internal temperature is achieved.
Equipment Safety
When melting chocolate over simmering water, ensure the bowl does not touch water. Steam contact with chocolate causes condensation and seizing.
Allergen Warning
Verify dark chocolate labeling for milk content. While 70% cocoa is typically dairy-free, some manufacturers add milk solids or process on shared equipment.
Pro Tips
Technique
When pouring the dark chocolate glaze, pour from the center and step away. The chocolate will find the edges in its own time. Do not assist it. Interfering creates uneven coverage and air bubbles beneath the surface.
Equipment
A probe thermometer is not optional — it is the difference between set and broken. The custard must reach 82C at the center before it is ready. Trust the instrument. Trust the cold.
From the chef
The winter fjord does not ask for your approval. Neither does this tart. I have taken the butternut squash — that blunt, honest vegetable — and placed it beneath a glaze dark as a January sky at three in the afternoon. The cinnamon whispers where others would shout. The honey offers sweetness like memory, not demand. This is not a dessert that seeks to please. It seeks to remain.
