I don't remember if the ALDI Irish Soda bread mix was a house brand or just something they had in store?
All the replies are very informative and IF I can't get the ALDI brand, I'll try the other alternatives.
Main thing that attracted me was that the Soda Bread mix only needed water, but I'm sure you could use ANY liquid as long as you don't put too much in.

That goes to the "light and fluffy"?
The Cache Lk recipes and proportion size calls for a 1/2 C water. This has always been a sore spot with me, because despite numerous attempts, I could never get ALL the mix wet and into dough ball shape with that amount of liquid.
Not enough liquid, you get dry ingredients and the bread isn't consistent in texture, too much liquid, the bread will end up burned on the outside and doughy in the middle.
I found that starting with a ½ C of liquid you could get a good mix and when it started to form a ball, I would add a few drops more IF needed to get a consistent mix. Better too little than too much at least in my experience.
Another thing I found is that you need to remember to start with a COLD pan with just enough oil to start the browning process, but not so much the dough gets saturated and greasy.
I bought a commercial grade non-stick 8” pan from Sam’s Club, just for bread making and frying fish.
I NEVER wash it, just wipe it out and store it in Cordura bag. NEVER use metal utensils either.
The Cache Lk recipes calls for medium heat but that can cause problems on a high BTU little stove, because in the case of my 20+ year old Peak 1 Multi-Fuel, the LOWEST setting, which they call simmer is more than enough to cook bread when used with a diffusion plate.
I go by the oil starting to sizzle. You want a LOW enough temp to cook the bread ¾ thru before the bottom becomes too browned. When the bread starts to rise and the top becomes “set”, I check the bottom for brownness and then flip it over. IF the bread doesn't turn without breaking up, then you have the heat to high and the center is still raw but the crust is too well done.
Once you get it right, you’ll know it. Better to have to raise the heat, and then start to hot and wreck the bread. I know from experience about that.
I go too early for the wild berry season, but I bet some wild blueberries/raspberries would be killer in a “breakfast” bread! The Cinnamon was a nice touch, but I made some at home with Pumpkin Pie Spice and that was good too.
