Why Fallow uses Thermapen
For the Fallow Chefs, temperature isn't guesswork — it's the foundation of consistent cooking.
Will Murray, co-founder of Fallow, says:
"The best way to learn is through a probe.
When I first started, I used a probe religiously because I just didn't want to get it wrong — it's a much more consistent way of getting the results you want."

Insert into food
Place the probe into the centre of any food or liquid to read the temperature.
Clean & close
The thermometer will automatically power off when set down.
Resting meat: the detail most people miss
One of the techniques Fallow chefs emphasise is understanding carryover cooking and when resting actually begins.
"Remove meat from the heat before it reaches its final temperature, allowing carryover cooking to finish the process."
The amount of carryover depends on doneness - Fallow Chefs recommend the following guidelines:
- Blue: +12–15 °C
- Rare: +10 °C
- Medium Rare: +6–8 °C
- Medium: +4–6 °C
- Medium well: +2–4 °C
- Well done: +0–2 °C
Doneness should be verified by touch, thermometer, and experience - not guesswork.Resting is essential. It allows muscle fibres to relax and juices to redistribute, resulting in a more tender and flavourful product. Ideally all meat should rest for a minimum of 10 minutes after cooking. Cutting too early sacrifices quality.In the restaurant, Fallow Chefs rest meat in a low, heated drawer so it stays warm without carrying on cooking too fast. At home - rest your meat on a wire rack set over a tray (so it doesn't sit in its own juices), tent it loosely with foil, and place it somewhere gently warm e.g. near the hob. Keep the foil loose rather than wrapped tight, as trapping too much steam can soften the crust you've worked for.
Learn like a chef
The Fallow Chefs encourage cooks to use temperature as a learning tool rather than relying solely on instinct.
"The best way to learn is through a probe."
Using a Thermapen allows you to connect what you see, feel and cook with the internal temperature of your food. Over time, you'll build confidence while consistently producing better results.
