It is fairly easy to make pumpkin purée. There are two methods: a) using the oven; b) using the microwave. The first takes about 60 minutes; the latter takes about 10. We like keeping things simple for making your meals. So we are presenting you the instructions for the second.
Cling film (plastic wrap)
Cut pumpkin in quarters, wrap with cling film. Pop it in the microwave, cook for 10 minutes; if they are small pieces, you may reduce the time or the contrary if the pieces are large. Carefully take out of the microwave, let cool before handling. Remove the plastic, discard the seeds, scrape the pulp and blend in a food processor and you are set!
