Pumpkin purée – an American novelty?

There is often a lot of debate in England about things that have become “Americanised”. Whether its Halloween, Christmas or even our language, American culture often has an impact on the UK’s and as a foodie I often look to trends in the US to see what is going to be popular for us in the next 5 or so years. If it happens over the pond, no doubt it will happen here too. Some people complain but I say lets embrace it!

Pumpkin – or more precisely pumpkin purée is just one of the gifts America has given us after the last few years.

Although we’ve had pumpkins in the UK for a very long time, and I’ve been carving pumpkins for Halloween as long as I can remember, cooking with pumpkin is quite a new thing. The fact that you can now buy Libby’s pumpkin purée in Asda rather than ordering it online is proof that more and more UK cooks are looking to America for inspiration in their cooking, particularly in the autumn. An apple pie just won’t do any more!

Cooking with Libby’s Pumpkin Purée

I’ve tried pumpkin pie a few times myself. The first time I tried to make one I was a little too impatient and topped the pie with whipped cream and marshmallow almost immediately after it had come out of the oven. It tasted fantastic but we did end up with a sticky puddle of cream where the pie once sat.

Since then I’ve been trying to come up with new ways of using the cans of pumpkin purée I’d been buying in bulk online (it’s cheeper that way…)

In years gone by, as well as the humble pumpkin pie I’ve also come up with recipes for Pumpkin Cookies with Cinnamon Chips and my own version of Starbucks Pumpkin Spice Latte (made with real pumpkin of course!) This year I was back in the kitchen experimenting with my latest haul of Libby’s pumpkin purée. Having had recent success with my Chestnut Brownie recipe (watch out for that in November…) I thought I’d apply the same principles to a can of pumpkin instead.

The moist pumpkin purée keeps the blondies fudgey and moist – there’s no chance of a dry cakey brownie here. The white chocolate adds a rich sweetness and the vanilla and spices help to marry the savoury pumpkin with the sweet chocolate and sugar.

Whilst the recipe does call for you to measure out your own individual spices, I have actually come across something rather spectacular – the “Signature Spice” mix at Waitrose. It’s a seasonal product and not all stores will be selling it yet but it’s a fantastic pre-made mix of festive spices. It’s perfect for all your festive baking! Feel free to substitute my spice suggestions for a heaped teaspoon of the Waitrose mix if you want to make life a little bit easier.

  • Pre-heat your oven to 180C and line a 9 inch rectangle baking tin with grease proof paper.
  • Place a couple of inches of water into a sauce pan and bring to the boil. Turn off the heat and place a bowl over the hot water.
  • Break the chocolate into cubes and add to the bowl, melt gently with the butter (also cut into cubes), stirring frequently.
  • Once the butter and chocolate have melted together, slowly stir in the sugar. You will be left with a glossy chocolate mixture.
  • Pour this into a large mixing bowl and beat in the pumpkin purée until smooth.
  • Leave the pumpkin and chocolate mixture for a few moments until cool and beat in the eggs.
  • Sift the flour, vanilla and spices into the batter mixture and fold gently until combined.
  • Finally, stir through the white chocolate chips
  • Pour the blondie mix into the lined tin.
  • Bake in the centre of the oven for 25 minutes or until the brownie mixture is set and a crisp top has formed with distinctive cracks.
  • Allow the blondies to cool in the tin before, cut into squares then carefully remove from the tin, peeling away the grease proof paper.

As with any brownie, my favourite way to serve these Pumpkin Spice Blondies is straight out of the oven with a big dollop of ice cream. You can’t beat the cold ice cream melting over the crisp outside of the blondie, then melting into the soft gooey centre. It really is heaven!

If you haven’t already jumped on the pumpkin purée bandwagon then hopefully this has convinced you – whether you live in the UK, America or somewhere in between!
