In a food processor pulse together gelatin and dry milk. Carefully add boiling water into machine and pulse again a few times.
Add shredded cheese and blend until it has melted and mixture is creamy.
Line a loaf pan with plastic wrap or parchment paper so all sides are covered so you can lift it out once hardened. (not necessary if using as a cheese sauce only)
Pour into loaf pan. Cover with plastic wrap and place into your fridge overnight to solidify. (if you want it as a solid block)
