Crush your pretzel sticks into bite-sized pieces — don't pulverize them into powder. Mix the crushed pretzels with melted butter in a bowl until everything's evenly coated. Press this mixture firmly into the bottom of an 8x8-inch baking dish.

Pop the pretzel base into the fridge for 15 minutes so it sets up slightly. Meanwhile, prepare your gelatin according to package directions using the cold water. This will take about 5 minutes total.

Remove the pretzel crust from the fridge and pour the prepared gelatin carefully over the top. Work slowly so you don't disturb the pretzel layer too much. Return to the fridge and chill for about 90 minutes until the gelatin becomes partially set but not completely firm.

While the gelatin sets, fold together your whipped topping, granulated sugar, lemon juice, and vanilla extract in a separate bowl. I personally add the lemon juice first because it helps prevent the whole mixture from tasting one-note. Gently stir until everything's combined with no streaks remaining.

Once the gelatin reaches that partially-set stage (it should jiggle but hold its shape), spread the whipped topping mixture evenly across the top. Don't worry if it looks thick — this is exactly right. Return to the fridge for at least 90 more minutes until everything's fully set.

Just before serving, arrange your fresh strawberry slices across the top in whatever pattern you like. Sprinkle the chopped pistachios and fresh mint leaves over everything for color and fresh flavor. The garnish adds both visual appeal and a little garden-fresh taste that makes people ask for your recipe.
