crispy critter have you heard of a calomondin citrus? they are cold hardy and delicious. they produce fruit like crazy too. small, extra tart, used in cooking and to make iced drinks, eatable straight for those who like tartness.
kumquats are also good hardy citrus. there is a wild one growing out in pretty much the open not far from here that takes the full force of winter. we get lows into the teens and some snow as well.
all citrus get planted on the south east side of trees to get that early morning sun to fight frost and snow. any thermal mass from rock helps when they are young, when they are older, they can handle much colder temps.
..... I had thought of building a south facing curved heat sink kind of wall, the tree as shelter never occurred to me. I am wondering how far outside of citrus climate you are.

In South Central Mississippi we have a citrus tree that is so hardy it has become a pest in many areas. We always called it a prairie lemon but The Book says that a more recognizable common name is hardy orange or trifoliate orange.
Pay no attention to wiki-reports that says that it isn't edible - my kids eat em all the time albeit with considerable lip-puckering. Other uses include making hardyorangeaid (which tastes remarkably like lemonaid) and batting practice for baseball. (It would probably work well for golf practice as well if you're into that sort of thing.)
My opinion is that these would make a decent lemon substitute, some sugar would help a lot!
The discouraging bits is the scant flesh/juice compared to number of seeds per fruit, the giant thorns on the plant, and also the gummy stuff in the peel which is somewhat hard to clean off.
