Using the magic square hole maker to make rectangular holes.
Two tenons will meet inside these large mortises, and possibly shakes hands. Or embrace. Haven't quite decided yet.
The hollow chisel mortiser (magic square hole maker) has an economy chisel from @leevalleytools mounted in it, and it cuts through this poplar incredibly easily. Then again, my basis for comparison is maple and walnut, so there is that.
This is about 5 minutes, condensed to 45 seconds.
