Doce de abóbora with walnuts
Doce de abóbora
Portuguese pumpkin jam cooked with cinnamon and optional walnuts. A sweet spread to refrigerate or freeze, rather than a home-canned preserve.
A Portuguese pumpkin sweet
Doce de abóbora is a pumpkin jam, often paired with cinnamon and walnuts. This version follows a household adaptation of O Pantagruel: one kilogram of sugar for one kilogram of pumpkin, with two cinnamon sticks. Those choices are kept together instead of being combined with a different syrup-preserve formula.

Drain before concentrating
The pumpkin is cooked in water first, drained and milled. Concentration then takes place with the sugar. The spoon-path test describes the texture: the pan base remains visible briefly after stirring. It is not a test of acidity or a canning endpoint.

Walnuts and keeping
Walnuts are optional, but a batch containing them must be identified for anyone avoiding nuts. Pumpkin preserves need refrigeration or freezing. High sweetness and a thick set do not supply a tested room-temperature canning method.

Keep the selected sugar ratio
The version here follows the author’s successful smaller batch, rather than the sweeter quantity also quoted from O Pantagruel. Those are two documented formulations, not a range to combine without deciding which one to make. The optional walnuts are folded into the finished mixture with the ground cinnamon.
The spoon path is a practical observation about consistency. Cooking longer changes concentration and texture, but does not by itself establish acidity or shelf stability. Once made, reserve a small refrigerated portion for eating and freeze the rest for longer keeping. Apply the general cooked-leftover limit of 3–4 days to the refrigerated portion, rather than borrowing storage instructions for a tested acidic-fruit jam.
Choosing the right preservation route
The storage instruction belongs to this formulation. Ball’s sweet pumpkin pickles and Bernardin’s pumpkin–pineapple compote have their own published boiling-water processes, with specified ingredient proportions, piece sizes, jars and processing schedules. Those recipes do not provide a canning method for this preparation. Keep this version chilled or frozen as directed.
History
This household adaptation was published by Constança Cabral in December 2010, drawing on O Pantagruel.

Risks and precautions · Standard risk
Spoilage during storage
Refrigerate or freeze pumpkin jam; do not home-can it for cupboard storage. Identify walnuts when used.
Hazard sourceRefrigerate or freeze pumpkin jam; do not home-can it for cupboard storage. Identify walnuts when used.
Control sourceRefrigerate or freeze pumpkin jam; do not home-can it for cupboard storage. Identify walnuts when used.
- Cook peeled pumpkin in water with a pinch of salt until soft.
- Drain thoroughly, pat the pulp dry with a clean cloth, and pass through a food mill.
- Mix with sugar until dissolved; add cinnamon sticks and cook, stirring.
- Stop when a spoon drawn across the pan leaves the base visible for a couple of seconds.
- Take off the heat. Stir in ground cinnamon and optional walnuts. Cool promptly in shallow containers and refrigerate at 4 °C or below; use that portion within 3–4 days under the general cooked-leftover rule. Freeze the rest. Do not home-can for cupboard storage.

Equipment
Food thermometer and refrigerator thermometer
A food probe measures the temperature inside food at the probe tip; a refrigerator thermometer measures the cold storage environment. They answer different questions and cannot establish acidity or validate a preservation process.
Freezer
A household freezer holds food in a frozen state for storage and selected texture or separation work; its batch-storage role differs from industrial equipment that freezes individual pieces separately.
Heavy stainless-steel (nonreactive) saucepan
A modern, portable stovetop pan with a stainless-steel cooking surface for sauces and other small simmering jobs. Size, cladding, lid, compatibility and care vary by model.
Refrigerator used as a produce store
An ordinary household refrigerator used to store selected fresh produce in vented crates or drawers, at low temperature and at a humidity chosen by the drawer. Not every crop benefits from cold.
