How to Prepare Offal and Remove Odor Certainly


Preparation is vital for offal. When you prepare it, milk is the best way to reliably remove the odor. This page introduces how to process various parts of the organs, including the heart, kidneys, and giara.

Offal in Finland

You can buy several offal at the markets in Finland. The most common ones are as follows


  • Tongue
  • Heart
  • Kidney


  • Tongue
  • Liver

When I traveled to the southern Finland, I saw pig’s feet and other offal in large supermarkets. Perhaps, more offal is sold in some areas.


Preparation is Vital

When you cook offal, preparation is vital. In Japan, the smell is quite mild. However, it is still important to prep the offal.

However, the offal is a different thing. The smell of offal is quite strong. If it is not handled correctly, the whole house will be filled with the smell of offal.

Milk to Remove the Odor

There are several ways to remove the smell of offal. The four most common are as follows

  • Sprinkle with salt
  • Boil in vinegar
  • Soak in milk
  • Soak in alcohol

Since alcohol is expensive in Finland, I tried all three except liquor. As a result, milk was the best.

On the other hand, the worst is boiling in vinegar. Boiling creates stinky steam that fills the whole house with odor. So, I do not recommend it at all.

Various Offal Preparations

Now let’s review the various methods of pre-processing offal.

The general process is as follows

  • Wash
  • Drain the blood

  • Boil
