Hi, you may have already come to a solution, but I will give my impute too
I lived with many housemates at one time and we did save scraps for our garden. First, it was nicer to just place them in a coffee container (currently we use the folgers plastic containers). The best reason for saving the scraps is so you don't fill up your trash can with smelly foods and create a long standing stink in the house. I personally don't like the smell of 'leftovers' in the house either so I tend to empty the container I use into the compost pile
about every 2-3 days and stir up the compost
with a pitch fork. I then rinse the container bring inside and reuse. If it helps to use a 'pretty' container, by all means make it beautiful on the outside
I suppose the winter months are the hardest for us Northerners I may just use a 5 gal pail this year and dump everything in it over the winter and leave outside. I don't really know any other options for the winter. Good luck!
