Cast Iron 6.5" vs. Round Edge Grill-Griddle-Ready Burger Tool Showdown for BBQs When it comes to crafting the perfect smashed burger, the Cuisinart 6.5" Cast Iron Smashed Burger Press stands out with its durable, heat-retaining design. Its round flat edge ensures even pressure, creating those signature crispy, golden patties that mirror restaurant-quality results. But what about the Round Edge variant? While it offers a similar function, its curved shape might slightly alter the burger's finish, suiting those who prioritize aesthetics over the classic flat press's bold, uniform look. As a team, we found both tools excel in their versatility-ideal for griddles, grills, or even tailgates. The cast iron model, however, holds a slight edge in consistency, especially when handling thicker patties. That said, the Round Edge version's portability and ease of cleaning make it a crowd-pleaser for casual setups. Ultimately, the choice depends on your preference: go for the cast iron if you crave bold, crispy perfection, or the Round Edge if you value adaptability and simplicity. Both are tools to elevate your BBQ game, but the Cuisinart's sturdiness and precision made it our top pick for serious foodies.
