For the Ice Cream:
Ingredients

500 mL whipping cream
500 mL milk
1/4 c brown sugar
3/4 c dark maple syrup
1 tsp maple extract (if you use light syrup)
pinch of salt
1 to 1.25 c wet walnuts

For the walnuts:
1.25 c walnuts
3/4 c maple syrup
pinch of salt

Method:

I worked with the walnuts first, as I want them cool when I add to the cream.
In a non stick pan, put the syrup and salt in and heat until bubbling. Add the walnuts, bring the mixture up to boiling again for 1 minute. Take from heat and cool.

Now the cream, mix the milk and brown sugar and extract together. To dissolve the sugar I warm the milk, and stir. You may want to cool this, but I found that mixing the cream was enough to bring the average temperature down enough to churn the creams. Mix the cream and salt in, then add to your ice cream maker. Churn until almost complete, add the the nut mixture. When done, place in a container and freeze for couple of hours. Enjoy.
