How to Use This Calculator

1

Weigh Your Brisket

Weigh after trimming. Full packers: 10-18 lbs. Flats only: 4-8 lbs.

2

Choose Your Temperature

225°F is traditional and forgiving. 250°F is faster with similar results.

3

Enter Your Serving Time

The calculator works backwards to tell you when to start cooking.

4

Plan for the Stall

At 150-170°F, brisket stalls for hours. This is normal - the calculator accounts for it.

5

Check Internal Temp

Done at 195-205°F. Probe should slide in like warm butter.

Why Does Brisket Take So Long to Cook?

Brisket contains collagen that must convert to gelatin for tender results. This breakdown happens between 160-205°F and requires extended time at low temperatures. Rushing the process results in tough, chewy meat.

The "stall" occurs at 150-170°F when moisture evaporates and cools the meat, pausing temperature rise for 2-6 hours. This is completely normal and essential for proper collagen breakdown.

Target internal temperature: 195-205°F. The probe should slide into the thickest part with no resistance, like warm butter.
