To prepare the poblanos, use tongs to roast the skin of the whole poblanos over an open flame (like a gas stove top or hob), turning the peppers until the skin is blistered all over. Once blistered, place each poblano in a plastic bag, and let steam for 15 minutes.

Use a dinner knife or similar to scrape off the charred skin of the peppers, then remove the stalk and seeds, and roughly chop.

Combine cream cheese, sour cream, and artichokes together in a food processor.

Add in the poblanos, and pulse a few times. Check for seasoning and add salt and pepper as necessary, then stir to mix. Transfer to a serving bowl.
