Place prepared pears into Thermo bowl with lemon juice and brandy and chop 3 sec/speed 5. Allow to infuse whilst you make the caramelised sugar syrup.
Place the sugar into a flat bottomed saucepan and leave on a low to medium heat (Induction 5) without stirring. Occasionally toss the sugar around and then as puddles of melted sugar start to appear, stir to combine without being too vigorous.
When fully melted, (but not burnt) add water (it will spit and separate) and stir until the caramel dissolves again.
Add caramel syrup to Thermo bowl with all ingredients except walnuts.
Cook 45 min/Varoma/Reverse/speed 1/spatter guard.
Add walnuts and combine 4 sec/speed 4.
Pour into sterilised glass jars. Seal and keep until use.
These make a very cute gift when wrapped with ribbon, a sprig of rosemary and tied up with a recipe for using it.
