    This recipe looks tasty! But it also could use some formatting to make it a bit more readable. Could you perhaps put some spaces in in between words? Thanks!

    Pumpkin? Do you mean squash? Also how big of a Squash are you using? Usually a 1-2 lb butternut squash takes about 40 min to roast in a 350 degree oven.

      I’ve just used ‘average’ sized squashes, and this has worked well for us. If you find this doesn’t work, let us know and we can modify the recipe.

    I just tried this recipe, and there is definitely something wrong with the time/temperature. After 20 minutes at 180, I had to turn the temp up to 365 for another 30 minutes. As a note, I used a fairly small butternut squash (maybe enough for 2 people).

    Are you guys sure your using the same conversion – 180 celcius would be fairly 350 Fahrenheit…
