This is super easy! All you need is fresh garlic, butter and a little bit of parsley (fresh is better, but dried is just fine).
50 g butter
1 clove of garlic
1 tsp chopped or dried parsley
1. Soften the butter. If you use a spreadable butter that's part cooking oil you can skip this step, but don't use milk free butter replacements if you can help it; they tend not to melt as nicely on the bread.
2. Press the garlic in a garlic press and add it to the butter.
3. Add the parsley.
4. Stir vigorously so it's nice and soft and creamy.
Multiply amounts as needed.
Serve on warm bread. Freshly baked or toasted both work fine. Or you can make garlic bread by taking a french baguette (I used a half sized whole grain one), slicing it diagonally but not all the way through—you want it to still hold together—and spreading garlic butter in the crevices. Heat in the oven at 200*C for about five minutes, until the bread is warm and the butter melted.
