In my kitchen I use a variety of spices, both powders and loose whole spices, numbering maybe 30 or 40 individual ingredients. Each one needs to be kept separate and reasonably well sealed while also being quickly findable, accessible and easy to replenish. Also, frequently, up to 10 or even 15 may be required to cook so the system needs to be easy to re-organise.
Current solutions that I have used and also that I have seen others use are very varied (from a bunch of packets in a cupboard, to spice rack arrangements, often with some rules that attempt to govern the system) but each one throws up problems, particularly when it comes to finding, replenishing and re-organising.
My kitchen, like most, has cupboards, drawers, flat surfaces and walls, all of which are capable of a holding objects or sets of objects that help to organise typical kitchen things such as spice collections. The time and cost spent implementing an excellent solution are considered well worth it.
What would be the best system of arrangement for the set of spices within the kitchen, taking the above requirements into consideration?
