Seasonal compote to go with custard pie

As Nancy alluded to already, citrus-based sauces. Cranberries are definitely seasonal. Or pineapple compote or sauce, pineapple is a holiday/seasonal fruit in some places!

This recipe appeared in this Hotline yesterday and I thought it sounded wonderful, and although it contains pears, they melt into the sauce. https://food52.com/recipes/1467-pear-brandy-walnut-cranberry-sauce

3 seasonal (winter or Christmas) ideas that could also be used for Thanksgiving:
1) marmalade with almonds, maybe spiked with brandy or liqueur
2) marmalade with poached supremes of orange
3) homemade vegetarian mincemeat
