Emerald Martini - a Poitin cocktail for St Patrick's Day (Irish moonshine)

My first entry into the #DrunkenShamrock2021 challenge is this riff on a Martini substituting the traditional Irish spirit Poteen/Poitin for gin. And of course it's green. Specs: 2oz poteen 1/2oz dry vermouth 1/4oz melon liqueur
