Some people manage to get it right the first time. Grant Hastings got it right when he built the first Hasty Bake Grill in 1948. This charcoal grill has changed little in function since then. Basically it is a closed box with a charcoal pan mounted so it can be adjusted close to the cooking grate for high, direct heat, or lowered as much as 14 inches to low temperature cooking. Add the removable heat diffuser and it grills, smokes or bakes indirectly. This makes the Hasty Bake design one of the most versatile on the market. There are many models and this version, the one of the least expensive, starts are around $1,000USD, so this isn't an inexpensive product. However, the quality construction (made in the US) means it will last a very long time.
