Starch management presents the primary challenge when forming vegetable patties without animal proteins or gluten networks to bind them. Potatoes contain high amounts of amylose and amylopectin. When boiled and mashed, these starches gelatinize. Cooling the mash slightly allows the starch molecules to retrograde, forming a semi-crystalline matrix that holds the patties together during pan-frying.
Dairy binds traditional mashed preparations through butter and cream fats, but plant-based oils substitute effectively here by coating starch granules and preventing excessive water absorption. Canola or grapeseed oil provides neutral flavors and high smoke points. Scaling the batch requires maintaining a 2-to-1 potato-to-brussels-sprout weight ratio to preserve structural integrity. Doubling the quantity means frying in separate batches to prevent pan crowding, which drops surface oil temperature and causes steaming instead of caramelization.
