I’d test drive it for you if I could! (I really miss mild Indian food)
But Aldi products get a lot of informal reviews so I recommend having a google around. I found some but not sure about etiquette of linking FB or the other place.
If you’re not a spice fan and unsure whether you’ll like it it might be better to make your own version to avoid ruining anything you put it on. Tinned tomatoes and spice packets are cheap. Or buy it and first try a smear on toast to avoid throwing out a meal.
Otherwise buy a tub of Greek yogurt to mix in or blend with some cheap fruit for a lassi. Yogurt and milk in general have a cooling effect because the fat insulates your mouth from the spicy oils, and Greek yogurt tends to be creamier and fattier.
If you’re worried about it not being spicy enough… I don’t know, never had that problem but you can add heat.
2% spices is quite a lot - might actually have a punch. Haven't ever tried it though. If looking for a very mild sauce, try the Chicken Tonight range or similar with added spice (by you). That is, fry up protein, add spices to taste or not, then add sauce from bottle and simmer as per instructions. If doing something like this, I use garam masala rather than chilli and that works very well. Plenty of taste but you still have tastebuds after eating it.
