I Love Offal

I love offal, or guts, and I try and eat it this way and that in Finland. For example, giara from a Middle Eastern market, pork large & small intestines from an Asian market, etc.

I also often cook easily available pork hearts and pork kidneys. Here are some tips on how to process various offal and how to get rid of the smell.

Tasty & Full of Nutrients

First, let’s review the taste and texture of pork kidneys. Pork kidneys are similar in texture to liver. However, they are a little firmer than liver and have a meaty elasticity. Pork kidneys themselves do not have a strong flavor. It has no peculiarities, and frankly speaking, it is easy to eat.

Rich in Vitamins

In terms of nutrition, pork kidneys are high in protein and rich in vitamins and minerals. However, it also contains a fair amount of fat. Even though, it is not a food that you would eat in large quantities every day, and there is no need to worry too much about it.

Pork Kidneys Stink

Now let’s check out raw pork kidneys.

In Finland, where I live, they are sold in two-packs of about 200 grams each.

They must have been lightly drained of blood, as there was a cut on the surface. In this state, they are not very tasty.

The Urine Line Inside Stinks

Next, cut a pig kidney in half. The whitish area in the center is the urine line. It seems that pig kidneys are very similar to human ones. It reminded me of my biology textbook when I was a student.

And this urine line smells so bad! It is a different smell from the smell of other offals. It smells like a pig farm. I am a little worried if I can really eat it, but it is ok. It is very easy to remove the smell. Let’s check out the preparation method right away.

Next, remove the urinary line using a knife. As shown in the photo, it is easier to place the part to be removed facing to the right and insert the knife. This way, you can remove the urine line, leaving the maximum amount of edible portion.

If you are very concerned about the smell, you should remove the white part as thoroughly as possible. It does not matter if some is left, but the urine line is still the main source of the odor. And it is also this part that produces lye when it is pre-boiled afterwards.

Wash with Water

Next, wash the pork kidney with water. At first the water will be quite cloudy. Change the water several times and wash.

Put in Milk

Now it is time to remove the odor. Place the pork kidneys in a bowl and pour the milk into the bowl. Leave it like this and wait for 30 minutes. If the room temperature is too high, place in the refrigerator.

Rinse with Water

Remove the pork kidneys from the milk and wash them well with water. After rinsing with water, check the smell. It should be quite weak. It is not possible to remove it completely, but if it is at the level that it is much better, this is fine. If the smell is still bothering you, soak it in milk again.

Boil

The last step is to boil them. Bring a large pot of water to a full boil. Once the pork kidneys are added, turn the heat to medium and boil them for a few minutes.

You will get quite a bit of lye. At first I thought that if I was going to fry them, I didn’t need to pre-boil them. But when I saw the amount of lye, I changed my mind. Boil them for a few minutes.

Wash with Water

Finally, rinse the boiled pork kidneys in water. In particular, carefully rinse the area where the urinary line was removed, as it is covered with lye.

This completes the preparation of pork kidneys and pork kidneys.

About Half the Weight after Prep

In this case, we used about 380 grams of pork kidneys. And after processing, it weighed 174 g. About half the weight.

After preparation, pork kidneys can be used as is for cooking. It takes a bit of work, but pork kidneys taste best when stewed with onions and ginger in a sweet soy sauce.
