Brown the sausages in oven proof fry pan and set aside
Place base ingredients in fry pan and place in oven for 15 min
Remove fry pan from oven and stir thoroughly, add sausages
Place back in oven for 30 min
Remove fry pan from oven and place over a medium heat element on the stove top
Stir in gravy ingredients and simmer until the gravy reduced by half
Boil spuds in a pot of water
A few minutes before the spuds are done add your cup pf peas
Once ingredients are just cooked set aside
Add milk and horseradish cream to pot and place back on the heat stirring constantly
Once the milk starts to boil remove from heat and add the spuds and peas back
Mash it all together with salt and pepper to taste
Can an ovenproof frying pan actually handle a dual-stage sear and simmer without warping the base? Standard heavy cast iron or clad stainless steel works best here, because thin aluminum pans will buckle during the initial 180 degrees Celsius oven phase.
Pan Sizing and Heat Retention
Crowding eight sausages into a standard 10-inch skillet prevents proper browning. Use a 12-inch or larger vessel so the meat releases moisture effectively instead of steaming in its own juices. Searing requires medium-high heat on the stovetop before transferring the pan to the oven for the 15-minute base roast.
Gravy Thickening Chemistry
Stirring all-purpose flour mixed with water directly into hot beef stock creates a starch suspension that thickens as amylose molecules gelatinize at roughly 95 degrees Celsius. Simmering the mixture until it reduces by half concentrates the beef proteins and onion sugars while cooking out the raw flour taste.
Mash Integration Mechanics
Boiling potatoes alongside peas until fork-tender simplifies the process, but draining thoroughly prevents excess water from ruining the texture. Heating the milk and horseradish cream gently before mashing ensures the starch cells do not become gluey from over-processing.
