Get all your items ready. Put them on the kitchen counter. This makes the work very easy. Clean your bowl and your whisk first.

Pour the chili sauce into the bowl. Use a large mixing bowl for this. The chili sauce is the red base. It smells very sweet and good.

This is the most important part. Use extra hot horseradish for the heat. Put it into the bowl with the sauce. Stir it in slowly at first.

Cut a fresh lemon in half. Squeeze the juice into the bowl. Watch out for any small seeds. Remove any seeds that fall in.

Sprinkle in the salt and pepper. Do not add too much at once. You can always add more later.

Use your whisk or a spoon. Blend it until it looks very good. Make sure the horseradish is spread out.

Taste a tiny bit of the sauce. Do you want more heat? Add more horseradish if you do. Be very careful with the spice.

Put the sauce in the fridge. Let it sit for one hour. Cold sauce tastes much better with shrimp. It also lets flavors blend.
