As we use no preservatives, it is recommended to eat our pastries within  3 to 4 days, as long as they are kept in the fridge. Macarons: just take them out of the fridge before eating them... Cannelés (or canelés): it is better to eat them the day you buy them, but you can keep them 3 to 4 days in the fridge as well. It is however better to make them re-heat in a pre-heated oven during 6 to 8 minutes at 160°C and let them cool down: they will regain their crispiness as on day 1 ;-) The sea-salted caramel can be kept in the fridge up to 2 months
