Equipment

Ingredients

  • 2lbs / 1kg Potatoes, peeled & sliced (see notes)
  • 2-3 heaped tbsp Goose Fat
  • 1 heaped tsp Flour
  • 1 bulb Garlic, cloves separated with skins left on
  • 3-4 sprigs Fresh Rosemary
  • Salt
  • Black Pepper

Instructions

  • Preheat oven to 410f/210c.
  • Place potatoes in a pot of cold water and bring to boil with a good pinch of salt. Boil until the potatoes are fork tender. Boil them slightly past the point you usually would. Softer spuds = rougher edges = extra crispiness.
  • Drain in a colander (do not rinse) and give them a shake to rough the edges. Allow them to steam dry for 5-10mins. The more they steam = the more moisture is leaving the potatoes = the fluffier they'll be. During this time, spread your goose fat in a suitably sized baking dish and place in the oven.
  • Mix 1 heaped tsp (not tbsp!) flour with a good pinch of salt and pepper then sprinkle over the potatoes, shaking a little more to ensure they’re evenly coated.
  • When your goose fat is smoking hot (literally), add your potatoes, ensuring they’re evenly spaced out. Add your garlic and rosemary and stir to coat everything in the fat. Work quickly so the fat stays hot.
  • Place in the oven for a total of 50-60mins or until golden and crispy on the outside. Take out and flip/re-coat in fat once/twice throughout to ensure an even coverage.
  • Serve with an extra sprinkle of salt to drawer out the final bit of moisture, just for extra crispiness.

Notes

a) What type of potato to use - I use Maris Pipers but any large white floury potatoes will do the job. Making sure your potatoes aren't too big is important. Smaller spuds = crunchier casing. Also making sure they're uniformly cut ensures they all cook at an even rate.
b) How to know when the goose fat is hot enough - A tip to check the goose fat is hot enough when it comes out the oven is to pop in a tiny bit of potato. If it rapidly bubbles, you're in.
c) Keeping the temp high - Whilst flipping the potatoes during the process is important, making sure the fat temperature stays high is just as important, so be quick! Also make sure adding the potatoes in the first instance is a quick process. Remember - hot hot hot!
d) How long to roast for -  Timings for these spuds will vary due to size, variety, other things in the oven etc just be vigilant throughout the process.
e) Is there anything I can use instead of Goose fat and get the same results? - The only other thing I recommend using is Duck fat. In terms of things such as olive oil, you just won't get the same results. Goose/duck fat is gorgeously rich in flavour and their high smoking point turns the potatoes extra crispy. Olive oil unfortunately does not work the same at higher temperatures for long periods of time.
