Aren't Pumpkin pie spices just a mix of easily available spices?
Yes!
A good recipe for pumpkin pie spice is
3 Tablespoons ground cinnamon
2 teaspoons ground ginger
2 teaspoons ground nutmeg
1 ½ teaspoons ground allspice
1 ½ teaspoons ground cloves.
Mixed spice is easily found and a very good replacement if you can't be bothered to make pumpkin pie spice. A common recipe for Mixed spice is:
1 Tablespoons ground allspice.
1 Tablespoons ground cinnamon.
1 Tablespoons ground nutmeg.
2 teaspoons ground mace.
1 teaspoons ground cloves.
1 teaspoons ground coriander.
1 teaspoons ground Ginger.
So not much in it at all.
Small flour tortillas are available. Sometimes they're next to the bread, instead of near the 'Mexican' food.
Pumpkin may not be out this time of year, but found in 'American' sections easily enough.
Popcorn , I like sweet and salty popcorn, so I'm no use. But I like to make my own too. I got an air popper from Lidl years ago and it's been great.
