- Combine all ingredients in a vacuum-sealed plastic bag.

- Gently shape two, one-inch thick hamburger patties. Sprinkle with salt and pepper. Place in a vacuum-sealed plastic bag and cook in a water bath set to 140°F for 90 minutes.
- Over medium-high heat, melt butter in heavy pan. Sear patties one minute on each side. While searing second side, add cheese to melt.

When cooking meats sous vide style, you do not usually include butter or other fats in the water bath, which is why we waited to add the butter until the searing stage. If you like your burgers extra garlicky or saucy, we think adding an extra tab or two of butter could really pay off.
For sous vide vegetable cooking, you often see recipes that include butter in the bag. Because we recommend adding only a touch of that maple syrup flavor on those beets, we would not add any more than 1 tbsp of the Maple Syrup Butter. You could also do half Maple Syrup butter and half unflavored butter if you wanted even less Maple flavor.
