Skipping the sauce chill – Not chilling the tartar sauce can result in a less flavorful experience. Allow it to chill in the fridge for at least 10 minutes before assembly.
Not measuring ingredients – A common mistake is eyeballing ingredients like dill or relish. Accurate measurements will ensure a balanced flavor profile in your sliders.
Ignoring assembly order – The order of assembly matters! Start with cheese on the bottom, followed by fish, then sauce to keep everything from sliding off.
