In a large pot of boiling water, quickly cook the cauliflower for 5 to 6 minutes, until barely fork-tender.
Drain and allow to cool slightly.
In a food processor or blender, chop the florets until they reach an almost mashed potato–like consistency.
Transfer to a bowl, and add the garlic, almond flour, and eggs.
Stir until well incorporated.
In a large sauté pan over medium-high heat, melt the butter. Begin to cook the fritters: Spoon some of the cauliflower into your hand, create a patty about half the size of your palm, and carefully lower it into the butter. You should be able to cook 3 or 4 at a time without crowding the pan.
Cook until browned on one side, about 3 minutes.
Flip and cook the other side, about 3 minutes more.
Serve garnished with the scallions.
