[Sca-cooks] Pear Mustard question

[Drucilla Meany-Herbert]

I want to make some pear mustard. Problem is I have no way to keep it 
cool. Is it necessary to keep pear mustard cool? I will be pureeing the 
(canned) pears, putting in mustard powder, adding a little Pear infused 
balsamic venegar and some white wine. My other mustards I don't need to 
keep refrigerated since they use dried friend (if any), no dairy, 
vinegar and/or wine but haven't made this before and am uncertain if I 
have to keep it cool for safety's sake.
