Begin by adding oil to your Instant Pot and turning it on to saute mode.
Once the oil is hot, add your chunks of stew meat and let brown, turning every few minutes for even cooking.
Once the meat starts to brown, add onions, garlic, carrot, and celery.
Saute for 3-4 minutes, or until the onions start to become translucent.
Add in dried chili pepper, spices, and curry paste and stir well. Cook for 1 minute until fragrant. Pour cup of water over top, scraping up anything that's stuck to the bottom. Turn off the Instant Pot.
Pour tomatoes and tomato sauce into the pot but do not stir (see note below). Secure the lid. Turn on Instant Pot to High Pressure for 32 minutes.
The Instant Pot will take a few minutes to come up to pressure.
When it finishes cooking, allow to natural release. Stir and enjoy.
