Crust: Preheat oven to 350F. Line the bottom of a 9-inch springform, pan
with 3-inch high sides, with foil. Butter and flour foil. Blend first 4
ingredients in processor until nuts are finely chopped. Add butter, yolk
and extract and blend until mixture begins to gather together. Press onto
bottom (not sides) of prepared pan. Bake until golden, about 25 minutes.
Transfer to rack, cool 10 minutes. Release cake pan sides from crust.
Gently turn out crust onto rack, peel off foil and cool. Place crust back
into pan and reattach pan sides. Maintain oven temperature.

Filling: Using electric mixer, beat cream cheese, 1 1/4 cups sugar, Scotch
and vanilla in a large bowl until well blended. Add eggs, one at a time,
beating just until combined. Pour into crust-lined pan. Bake cheesecake
until set at edges, but centre 3-inch area still moves slightly when pan is
shaken, about 50 minutes. Place on rack and cool 10 minutes.

Mix sour cream with remaining 1/4 cup sugar. Spoon sour cream mixture over
cheesecake. Bake 10 minutes. Transfer cheesecake to rack and cool 10
minutes. Run small sharp knife around top edge of pan to loosen cake.
Chill overnight. (Can be made 2 days ahead)

Topping: Stir sugar and 2/3 cup Scotch in heavy large saucepan over medium
heat until sugar dissolves. Increase heat and boil without stirring until
syrup turns golden, occasionally brushing down sides of pan with pastry
brush dipped in water and swirling pan. Add 2/3 cup cream and butter
(mixture will bubble) and stir until smooth. Cool 10 minutes. Stir in 1
tablespoon Scotch. Let stand until cool, but still pourable, about 2
hours. Mix in 1/2 cup almonds

Spoon all but 1/2 cup butterscotch topping over cheesecake (remove
remainder for another use) Sprinkle with remaining 1/4 cup chopped almonds.
