Could have been Canadian bacon made from the loin.
Here's a recipe for using loin (this is based on 4 lbs and pork so adjust accordingly):
1 gallon/4 liters water
1.5 cups/350 grams kosher salt
1 cup/225 grams sugar
1.5 ounces/42 grams pink salt (about 8 teaspoons)
1 large bunch fresh sage
2 garlic cloves, peeled and lightly smashed
Combine all brine ingredients in large enough pot to hold loin and brine (Do not add loin yet). Simmer to dissolve the salt and sugar. Remove from heat and let cool to room temp. Refrigerate until chilled.
Put loin in brine and weigh it down with a plate to keep submerged. Refrigerate for 48 hours.
Take out the loin (discard the brine), rinse it under cold water and pat dry. Place on rack set over a plate or tray and refrigerate uncovered 12-24 hours.
Hot-smoke the loin to an internal temp of 150 degrees F. If you don't have a smoker, place in oven no higher than 250 degrees. Allow to cool, cover and refrigerate for up to 10 days.
