The night before you plan to cook the oxtails, place them in a container
and season with browning, onion powder, all purpose seasoning, sliced
onions, pepper, tomatoes, and green onions. Let oxtail marinate in
fridge overnight.
In a large pressure cooker, heat 2 tbsp canola oil over medium high
heat. Remove the oxtails from the fridge and separate the oxtails and
the seasoning. Working in batches, add oxtails to the pot and brown on
both sides, approximately 3 minutes on each side. Make sure that you do
not overcrowd the pot and make sure that the oxtails are evening
dispersed in one layer. Remove the oxtails from the pot and place them
in a covered dish.
Reduce the heat to medium and add remaining oil and the reserve
seasoning from the marinade. Allowing the seasoning to cook, then add
the pimento, all spice and oxtails. Add water and cover the pressure
cooker. Follow your pressure cooker’s directions and pressure the
oxtails for one hour. The oxtails are done when they are easily pierced
with a fork. Note: You don’t want the oxtails to be fall apart tender at
this point because they still need some additional cooking.
Next, remove the pressure cooker cover and add tomato paste/ketchup,
sugar (optional), and butter beans (optional), plus remaining seasoning.
Bring heat to a boil then reduce to a simmer. Cover with a regular pot
cover. Simmer the oxtails for 20-30 minutes, until the sauce thickens
and the oxtails begin to fall off the bone.
For the mashed potatoes, peel potatoes and cut in half. Bring about
4-6 cups of water to a boil and after adding salt to the water, add
potatoes and boil for 15-16 minutes. Remove from water and transfer
cooked potatoes to a large bowl. Add milk, butter, and chopped herbs.
Mash potatoes with a potato mash or ricer until potatoes reach desired
consistency. Serve immediately.
