I made a Tikka Masala from scratch this weekend! It was surprisingly easy, and shockingly close to the real thing. I followed this recent video by Brain Largerstrom.
The spice mix was just cumin, paprika, curry powder, garam masala, and chilli flakes.
90mm x 45mm is what’s available near me for framing timber. And yes it’s more accurate.
Millimetres in general are used heavily in construction, everything is stated in them, even into the thousands where people normally would have switched to metres.
