Roasting, Grilling & Low-and-Slow Timing: Cook Times, Resting, Yields & Dinner Schedules

What you'll build

What you will be able to do

Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.

• Estimate roasting times for five fictional roasts with the card's base + minutes-per-kg rule, compare them with a thickness rule that grows with the square of the thickness, plan with the longer estimate in 5-minute blocks and show the plan as h:mm.
• Estimate carryover from the weight with a capped rule from Mira's binder, subtract it from each card's target to get the pull temperature, set resting times with a minimum and work back from the carving time to the moment each roast leaves the oven.
• Plan four smoker cooks for a fictional backyard lunch: total hours from weight, a stall buffer and resting, the clock time to start each cook (across midnight with MOD), whether that is the day before, and when to light the smoker.
• Look up each item's time in a fictional thickness table with an approximate XLOOKUP that rounds up to the next row, count the bags with ROUNDUP, work out how many bags fit in the bath and how many batches each item needs.
• Turn Mira's cooking log into weight loss per cook, pool the yield for each cut with SUMIFS, work back from the cooked portion each guest gets to the raw weight per guest, and round the shopping amount up to the next 100 g.
• Work back from a 19:30 serving time to the moment each dish leaves and enters the oven, flag dishes whose card temperature clashes with the roast, and let a formula name the dish that has to go in first.
• Turn an overnight probe log into the rise per hour, spot the stall, measure the average rise with SLOPE and forecast when the trend since the stall reaches the card's target, both in hours and as a clock time.
• Plan a fictional holiday dinner backwards from 18:00: start offsets, clock start times, the wait from kitchen start for every task, and a stacked bar chart that turns the list into a Gantt-style timeline.
