Tuna Steak Temperatures

To get the most out of a tuna steak you need to be careful with the temperatures. This includes making sure the fish is kept cool before cooking and the final core temperature.

What to look for when buying Tuna Steak

When buying tuna steak’s you want to shop at a reputable, knowledgeable, good quality fish supplier. The fish should smell fresh and mild, not fishy. The flesh should also be pinkish and not grey.

Make sure to buy your fish last from the supermarket. This way it will stay cooler for longer. Refrigerate as soon as you get home.

Tip: Bring an ice cooler in the car.

Tuna Steak Cooking Temperatures

Now you have bought your fresh tuna steaks, its time for cooking. My favourite way to cook tuna steak is rare to medium rare. Anything above medium you will start to lose its luxurious texture and dry out.

The cooking time varies by the thickness of each tuna steak and how hot your pan is. For beginners the best way to know when your tuna steak is cooked is by using a probe. You want to use a fast, reliable probe like this AMAGARM probe. This is because tuna steaks overcook very quickly.

Rare – 38c to 43c | 100f to 110f

Medium Rare – 43c to 49c |110f to 120f (recommended)

Medium – 49c to 54c |120f to 130f

Medium Well – 54c to 60c | 130f to 140f

Well done – 63c+ | 145+ (not recommended)

How To Cook Quinoa

Cooking quinoa is easy and perfect for batch cooking. I normally cook a few portions at a time to eat over the next few days. For people who would rather cook their quinoa then buy pre cooked, here’s a quick recipe for you.

Serves 2 | 22 Minutes | 250-300g cooked weight.

Ingredients

• 100 g Quiona 
• 200 ml Water
• 1 pinch Sea Salt

Instructions

1. Thoroughly rinse the quinoa in a fine sieve under cold water for 30 seconds.
2. Add the quinoa, water and sea salt to a pot. Quickly bring to a boil then turn down to a light simmer. Cook for 15 minutes until the quinoa has absorbed all the water. 
3. Turn off the heat and place a lid on the pot. Leave to steam for 5 minutes. 
4. Take of the lid and fluff the quinoa with a fork. Taste for seasoning then serve.
