Season the beef short ribs with Himalayan salt and white pepper.
Dust them with all-purpose flour, ensuring each rib is lightly coated.
Heat the grapeseed oil in a large pot over medium-high heat.
Brown the ribs on all sides, which takes about 5 minutes per side.
Once browned, remove the ribs from the pot and set them aside.
Add the carrots, celery, and green pepper to the pot, stirring for 2-3 minutes until they soften slightly.
Return the ribs to the pot, pouring beef stock over them.
Reduce the heat to low and cover the pot.
Let it simmer for around 2 hours until the meat is tender and easily separates.
Serve the ribs hot, alongside your choice of sides such as mashed potatoes or a fresh salad.
