Choose a grind with enough fat to keep the patty moist while cooking. For most home cooks, an 80/20 (lean-to-fat) blend is ideal: it provides good flavor, renders fat as the burger cooks, and helps form a tender interior without being greasy.
If you prefer a slightly leaner burger that still stays juicy, 85/15 is acceptable, but expect a firmer texture and a bit less juice. Avoid very lean grinds (like 93/7) for classic burgers; they dry out easily and need added binders or sauces.
Mixing fresh ground beef at home from selected cuts (chuck, short rib, brisket) gives the best control over flavor and fat content. If buying pre-ground, check packaging date and fat ratio.
With the right grind and gentle handling, you’ll get a juicy, flavorful burger every time.
